2. New Features and Enhancements  
The following sections detail new features and enhancements in ScreenOS 5.0.0  
releases. For a complete list and descriptions of new features and enhancements  
in ScreenOS 5.0.0, refer to the Juniper Networks NetScreen ScreenOS Migration  
Guide.  
2.1 New Features and Enhancements in ScreenOS 5.0.0r9-FIPS  
None.  
2.2 New Features and Enhancements from ScreenOS 5.0.0r8  
Destination NAT Enhancement – An enhancement has been added to the  
destination NAT feature to allow ARP responses for addresses that are on the  
same subnet as the device's interface. For further information on this feature  
please see the Juniper Networks/NetScreen Knowledgebase.  
Scan Engine Update for Juniper NetScreen-5GT – ScreenOS now embeds  
Trend Micro’s new scan engine version 7.0 to provide better scanning coverage  
and increase performance. All previous versions of pattern files will be compatible  
with this new version.  
As part of the Scan Engine Update, Juniper Networks implemented the ability to  
increase scanning coverage using the following commands:  
• set av http skipmime  
• unset av http skipmime  
Note: The feature may impact performance on the device for traffic that may  
match embedded text in HTML packets.

Juniper Networks  
NetScreen Release Notes  
According to Trend Micro, the categories of viruses bypassed include HTML and  
Javascript. However, the subset of the bypassed viruses can be described as the  
following:  
Javascript/Jscript/HTML embedded in HTML code (having HTTP content  
type of text/HTML) AND is accessed through a script-enabled browser from a  
remote web server (via HTTP).  
For example, anti-virus scanning would NOT be bypassed for the following  
scenarios:  
1. Javascript/HTML malware which is stand-alone in a *.js file  
2. Javascript/HTML malware propagating via email attachments  
So the viruses bypassed would be all Javascript and HTML based viruses, but  
accessed or contained with the above characteristics in HTTP traffic only.  
2.3 New Features and Enhancements from ScreenOS 5.0.0r6  
New Hidden Command - In response to the NISCC VULN 236929, a new  
hidden command is implemented in this release. The command is set/unset flow  
check tcp-rst-sequence. By default, the command is not set. This command  
alters the device’s response to potentially spoofed TCP RST packets.  
2.4 New Features and Enhancements from ScreenOS 5.0.0r1  
Juniper NetScreen-5GT - Dial Backup, Dual Untrust, OSPF, and BGP are now  
available in the 10-user version. Previously these features were only available in  
the Plus version.  
Juniper NetScreen-5GT - The Extended version provides the same capabilities  
as the Plus version with additional features: High Availability (NSRP Lite), the  
DMZ security zone, and additional sessions and tunnel capacity. For information  
on these features, refer to the Juniper Networks NetScreen ScreenOS Concepts &  
Examples Reference Guide for ScreenOS 5.0.0.  
Note: You must register your product at www.juniper.net/support so that certain  
ScreenOS features, such as antivirus or deep inspection, can be activated on the  
device. If you already have an account, enter your user ID and password; if you are a  
new Juniper customer, create your account first. To register your product, you need  
the model and serial number of the device. After registering your product, confirm that  
your device has internet connectivity. Issue the CLI command exec license-key  
update to make the device connect to the Juniper server to activate the feature.

4. Addressed Issues in ScreenOS 5.0.0  
The following sections detail addressed issues in each release of 5.0.0.  
4.1 Addressed Issues in ScreenOS 5.0.0r9-FIPS  
• 03875 – After attempting to update a new configuration to the device from  
Security Manager to the primary Juniper NetScreen-5200 system in an  
active-passive HA pair of Juniper NetScreen-5200 systems, the primary  
system failed. The backup system failed a minute and a half later.  
• 03637 – When the firewall acted as a TCP proxy server, and if the server  
returned the syn-ack packet too late in response to a syn packet, the relevant  
firewall flow resource could be released too early and caused the firewall to  
fail.  
• 03632 – When you have two VOIP phones connected to a trust and an  
untrust zone on a Juniper NetScreen-5GT running in extended mode, and  
you tried to place a call, the phone obtained its IP address from a DHCP  
server.  
• 03607 – When two 5000-24FE system running in an NSRP active-passive  
transparent mode, where the e2/25 and e2/26 interfaces connected to a  
switch, stopped passing traffic and displayed the following meaningless  
message on the console:  
get log system saved  
• 03600 – If you issued the get tech command for a Juniper NetScreen-5400  
in an NSRP active-passive configuration while the system was busy, the  
system failed.  
• 03569 – A Juniper NetScreen-5000 Series system could fail due to flow  
memory corruption from out-of-order TCP packets.  
• 03558 – A trace route or ping operation sometimes caused memory  
corruption, causing the device to fail.

system added a new user instead of changing the name of the existing user.  
• 03295 – When you issued a get interface command or similar commands,  
ScreenOS truncated interface names that had too many characters.  
• 03294 – When you issued the command get log traffic | inc on a Juniper  
NetScreen-5200, the system failed.  
• 03281 – When you performed an incremental SPF (Shortest Path First)  
operation for an OSPF virtual routing instance, the device failed.  
• 03278 – When updating a dynamic VPN tunnel’s peer gateway IP, a new

NetScreen Release Notes  
• 02580 – When you created a new custom service, and then configured a VPN  
using IKE, the Proxy ID setting in the VPN Autokey IKE configuration  
incorrectly defaults to the new custom service, and not the ANY service.  
• 02555 – The system incorrectly created sessions for embedded ICMP  
packets.  
• 02530 – A TCP stack error caused the BGP neighbor state to change to the  
Idle state before the BGP holddown time value (default of 180 seconds)  
expired. The BGP neighbor state, a setting determined by whether the  
current BGP routing instance, can detect its neighbor to be active, and is not  
supposed to render the neighbor Idle until no neighbor response occurs after  
the holddown time elapses.  
• 02519 – In an instance where an active-passive HA pair of Juniper  
NetScreen-208, the SA (Security Association) went out of sync, the backup  
device became corrupted and the device failed because memory on both  
devices became corrupted.  
• 02498 – The status link LED incorrectly indicated that the Fast Ethernet  
port on both the Juniper NetScreen-500 and Juniper NetScreen-200 was  
running at 10 Mbps while the physical link was correctly running at 100  
Mbps.

policy where the source was Trust and the destination was Trust, then the  
groups were not displayed properly in the Policy list.  
• 02152 – In instances where you created an intra-zone policy with the source  
zone was Trust and the destination zone was untrust and that used multiple  
addresses, the Policy list displayed the same entity for both the source and  
destination in the policy.  
• 02101 – Messages logged with a VIP (Virtual IP) incorrectly indicated the  
VIP connection connected and disconnected repeatedly, indicating the  
presence of a false positive even though the VIP connection sent  
acknowledgment responses to the query. The messages displayed  
continuously were:  
VIP cannot be contacted.  
VIP is now alive.

inter-area summary route is one value that encompasses a range of route  
prefixes contained in multiple routing areas.  
• 01523 – An OSPF virtual routing instance sometimes unexpectedly dropped  
routes.  
4.2 Addressed Issues from ScreenOS 5.0.0r8  
• 40292 – A potential cross-site scripting attack existed in the anti-virus scan  
engine when processing compressed files.  
• 39458 – You could not configure 16 concurrent anti-virus messages, the  
expected maximum number of messages allowed when running the anti-  
virus Scan Manager utility in the WebUI.  
• 39087 – In certain circumstances, the first attempt to access a TCP  
application through a Juniper NetScreen-5000 system with authentication  
failed when the ARP entry for the application was not present.  
• 38193 – A Juniper NetScreen-5GT could not access common public web sites  
when an administrator performed an anti-virus scan for HTTP on the device.  
The attempted connections will expire after they exceed the time out  
threshold for connection attempts.  
• 37933, 37945 – If a number of different attacks entered the Juniper  
NetScreen-5000 Series system over a period of time, the system sometimes  
began to drop packets.  
• 36708 – You could not view the traffic logs for a Vsys if you entered the Vsys  
as a root admin user.  
• 36670 – You could create more VLANs on a Juniper Networks security  
appliance than the number of VLANs the device officially supported.  
However, doing this sometimes caused unexpected results. Refer to the  
specifications sheet for your NetScreen product to learn how many VLANs it  
supports.  
• 36494 – Upon startup, Juniper Networks security appliances using PPPoE  
sometimes generated a warning message informing that the interface  
gateway command was invalid. This is a result of the gateway changing

Juniper Networks  
NetScreen Release Notes  
whenever the device restarts and does not effect the normal operation of the  
device.  
• 36473 – Restarting a Juniper Networks security appliance while it was  
performing an operation in flash sometimes damaged the data on the device  
and caused the device not to restart or to lose the configuration.  
• 36235 – Adding the pre-defined service entry "ANY" in a multiple service  
policy sometimes resulted in a system fail.  
• 36095 – You could not change the IP address of an interface if a VIP or MIP  
was configured on that interface, and the VIP or MIP was used in a policy  
configuration. DHCP and PPPoE could not change the interface IP address if  
a VIP was configured using the same-as-interface option.  
• 35977 - (Juniper NetScreen-5XT only) The Juniper Networks security  
appliance sometimes dropped TCP traffic because it miscalculated the length  
of the tcp-syn-check.  
• 35904 – (Juniper NetScreen-5GT only) Juniper Networks security  
appliances needed to support two incoming IPSec keys. When the software  
lifetime was in use and after the re-key was successful, the device should  
have permitted traffic using older SA's to traverse the device.  
• 35735 – A root administrator could not manage the root system from a host  
that resided on a virtual system.  
• 35624 – If you set the negotiation mode on a 10/100 Ethernet port to Full  
Duplex and configured the holddown time on the interface to less than one  
second, it caused the interfaces to go up and down.  
• 35615 – (Juniper NetScreen-5GT only) Any policies within the device  
indicated traffic shaping was active for the policy. Issuing a 'get policy' CLI  
command displayed an "X" under the "T", for traffic shaping, in each policy.  
However, issuing a 'get policy id <number>' CLI command indicated that  
traffic shaping was turned "off".  
• 35528 – In an active-passive NSRP configuration, you needed to set a  
manage IP on both devices to enable each device to connect to the  
entitlement server and retrieve signatures.  
• 34279 – (For Juniper NetScreen-5000 Series) Juniper Networks security  
appliances sometimes unexpectedly dropped traffic that was processed by  
the CPU module and that matched a policy in which the “Diffserv” option  
was enabled.  
• 29619 – When you used the CLI to configure SCEP, you could not specify an  
already defined Certificate Authority as the recipient of the certificate  
requests.  
• 02940 – The device sent out multiple SNMP traps associated with the same  
event after you changed the source interface for SNMP operations.

Juniper Networks  
NetScreen Release Notes  
• 02926 – The number of syslog messages sent per second from the Juniper  
Networks security appliance were being limited by an internal process.  
• 02924 – SMTP (Simple Mail Transfer Protocol) queued emails on Microsoft  
Outlook 2003 clients timed out when a policy had the anti-virus option  
enabled because you could not perform more than one SMTP transaction  
within one session.  
• 02909 – Embedded ICMP caused the DIP (Dynamic IP) pool memory leak  
traffic flow to stop because the DIP allocation failed after no ports were  
present.  
• 02897 – The WebUI displayed the autokey IKE list incorrectly in instances  
where a listing of 5, 10, 50, or 100 entries were in the list. It displayed only  
20 items per instance.  
• 02896 – An SA (Security Association) sometimes was visible in the wrong  
Vsys in an environment where two Vsys both had non-active dialup VPNs  
configured.  
• 02880 – If you enabled the anti-virus option on a policy, and ran the  
windowsupdate.microsoft.com utility on the policy, the utility hung and the  
console displayed the Network Error page. The utility worked only when the  
the policy had the anti-virus operation disabled.  
• 02874 – A fail occurred when the device prevented packets with the wrong/  
inactive virtual MAC address from being forwarded.  
• 02853 – The WebUI inadvertently allowed adding a subinterface in  
transparent mode causing the device to fail.  
• 02841 – The device inadvertently displayed an inactive route as active in an  
environment where two route-based VPN unnumbered tunnels mapped to  
one VSI. This behavior only occurred when this VSI was assigned to the  
Untrust zone that had an IBGP routing instance configured inside the  
network.  
• 02829 – When obtaining a traffic log using a specific IP address on an SSH  
session by issuing the get log traffic | include command, the device failed.  
For example, if you connected to the device using an SSH session and you  
issued the following command (which contains an explicit IP address):  
get traffic log | include 10.1.1.10  
the device shut down and failed.  
• 02824 – Custom zones incorrectly supported half the number of IP address  
book and group entries than predefined zones did.  
• 02823 – When applying the snoop filter with a destination IP address and  
destination port, the filter did not work.

Juniper Networks  
NetScreen Release Notes  
• 02822 – The DHCP utility did not work on one of the redundant interfaces  
on a device. The interface did not appear in the DHCP environment in the  
WebUI.  
• 02814 – The SNMP interface index values were inconsistent through the  
SNMP tree. Interface index values uniquely identify each interface.  
• 02805 – Under certain traffic conditions, some DNS and HTTP session  
timers were set with higher values than the DNS and HTTP service  
timeouts.  
• 02796 – When the device sent out a trap that indicated an SNMP  
authentication failure when OSPF was enabled, the device failed.  
• 02788 –In certain situations, an Juniper NetScreen-5000 device failed when  
it received a high number of bad IKE packets.  
• 02786 – If the packet that had both a destination broadcast subnet IP  
address and a MAC multicast address attempted to enter the device, the  
device dropped it.  
• 02785 – A Juniper Networks security appliance failed continuously because  
an interface on the device did not check that the PPP (Point-to-Point  
Protocol) encapsulation functioned properly.  
• 02771 – Traffic through a MIP (Mapped IP) address with both source-based  
routing and traffic shaping enabled failed.  
• 02765 – If a configuration is pushed to the device by Security Manager and  
the heartbeats to the device are lost, the device would invoke the  
configuration rollback feature because the heartbeat missed threshold was  
too short.  
• 02740 – The Security Manager Log Viewer did not display data in the Alert  
column. The Alert column now correctly displays traffic logs associated with  
policies that have the Alert setting selected.  
• 02736 – The Mgt-IP on a VSI replied with a virtual MAC address instead of  
a physical MAC address for the Ident-reset.  
• 02734 – When you performed an SNMP walk operation on the Policy MIB,  
the procedure incorrectly displayed an integer to represent the custom  
service. It now correctly displays a string to represent a custom service in the  
Policy MIB.  
• 02730 – For external LSAs (Link State Advertisements) that have a  
forwarding address, the priority for a forwarding route incorrectly used the  
interface cost as the priority value rather than the metric of intra- and inter-  
area OSPF routes. The metric is the correct value to use for setting a route  
priority.  
• 02718 – Importing a device into Security Manager failed because the  
heartbeat timeout was exceeded and was not user configurable.

Juniper Networks  
NetScreen Release Notes  
• 02709 – When you set a manual VPN authentication setting to NULL on a  
Juniper Networks security appliance, the device failed because a Null length  
is invalid.  
• 02707 – When performing an anti-virus scan on a Juniper NetScreen-5GT  
device, the device displayed an error-constraint-drop status.  
• 02699 – When multiple interfaces belonged to different Vsys had the same  
IP address and subnet mask, VPN traffic to these subnets could pass to the  
wrong Vsys.  
• 02609 – The primary Juniper NetScreen-5200 device in an active-passive  
NSRP cluster failed, which caused a failover from the primary to the backup  
device.  
• 02694 – ScreenOS did not send discovered SCREEN occurrences to Security  
Manager when Security Manager imported a configuration from a device.  
• 02692 – The DIP (Dynamic IP) allocation failed and halted traffic entering  
the device, requiring the DIP allocation mechanism to be reset every two  
hours.  
• 02688 – The CLI provided no maximum value check for BGP hold time  
entered on a device, incorrectly allowing you to enter any value for the hold  
time. If the value was greater than the maximum hold time setting of 65,525,  
the device incorrectly accepted the value, and the output from the get hold-  
time command incorrectly displayed it as a negative number.  
• 02687 – Traffic shaping did not work properly when the traffic shaping  
policies traversed a route-based VPN on a device.  
• 02685 – You could not unset the sql alg using the unset flow sql-alg  
command on Juniper NetScreen-5000 Series devices.  
• 02679 – Some devices generated multiple logs for information associated  
with the self log.  
• 02670 – When a Juniper NetScreen-5XT device obtained a new IP address  
from a DHCP server, one of the static routes did not update the default  
gateway with the proper IP address and DHCP payload information  
assigned to the device.  
• 02668 – A VPN tunnel incorrectly displayed two different ESP sequence  
numbers which are associated with two different ASICs on the Juniper  
NetScreen-5000 Series devices.  
• 02664 – Packets were sent out with the MAC address of the inactive VSI  
instead of the active VSI address in an active-active VSI cluster.  
• 02663 – You could not manage two of the secondary IP addresses on an  
interface of the Juniper NetScreen-100p in the WebUI.  
• 02660 – After importing a CA (Certificate Authority) certificate into a device  
and then rebooting the device, the device removed the certificate.

Juniper Networks  
NetScreen Release Notes  
• 02655 – The event log timestamp changed to Daylight Savings Time (DST)  
even though DST was not enabled.  
• 02642 – After configuring SCREEN setting thresholds on a device using the  
WebUI or CLI, the get config | include <screen_settings> command did  
not display the configured settings.  
• 02641 – The PKI IKE memory pool on a device had a memory leak caused by  
the Security Manager agent.  
• 02637 – A session allocation with less than 1,000 sessions on a Juniper  
NetScreen-5000 Series device failed.  
• 02629 – When running a get config all command and redirecting the output  
to a file on the TFTP server when the Trust interface as the source, the file  
was not transferred correctly.  
• 02627 – The policy move page only displayed the first 20 policies, and  
therefore you could not move a policy from the initial screen from where you  
copied the beyond the 20 policies displayed.  
• 02624 – An anti-virus scan failed to scan .RAR files on a Juniper  
NetScreen-5GT.  
• 02621 – When a Ping request is initiated through a VPN tunnel to a MIP  
configuration on a loopback interface, the ICMP reply through the tunnel did  
not get translated back to the MIP address.  
• 02680 – The SNMP name command inappropriately propagated across the  
NSRP cluster.  
• 02682 – When using the WebUI to set information on the backup device, the  
primary SNMP device was inappropriately deleted when using the unset  
VSD ID 0.  
• 02606 – A ping packet through a tunnel in an NSRP environment between  
two Juniper Networks security appliances failed after a failover until you  
performed a rekey operation.  
• 02581 – You incorrectly could define the same IP address to multiple  
loopback interfaces over multiple subnetworks by running the set vrouter  
trust-vr ignore-subnet-conflict command on a device. Juniper Networks  
security appliances support defining multiple loopback interfaces on the  
same subnetwork, but not with duplicate IP addresses.  
• 02578 – A PPPoE (Point-to-Point-Protocol-Over-Ethernet) connection on a  
device incorrectly sent an acknowledgment for an unnumbered PPP session.  
The correct response to an unnumbered PPP session is a NAK (Non-  
Acknowledgment).  
• 02552 – Policy authentication with an external authenticating server could  
run into the same memory corruption when authentication failed and caused  
the firewall to fail.

continuously when no failure on the primary device occurred.  
• 02543 – A device rebooted because of an improperly processed checksum.  
• 02542 – When upgrading a Juniper NetScreen-5GT from ScreenOS 4.0.0r4  
to ScreenOS 5.0.0r3, a PPP connection from a Windows XP client to a  
Windows 2000 server stopped working.  
• 02536 – The priority value on a WebTrends syslog message varied from  
device to device.  
• 02531 – After changing manage options in the Untrust interface with a  
DHCP client configured, the device renewed its IP address with the DHCP  
server, causing loss of configuration of MIPS, DIPs, and VIPs.  
• 02509 – A memory leak in the NSRP synchronization process between two  
devices caused some FTP sessions to stop working.  
• 02477 – You cannot configure the NSRP Lite feature through the WebUI  
even though you applied an NS-5GT extended key.  
• 02457 – The URL request function that sent content to a WebSense server  
sometimes engaged the CPU on a device for too long causing the device to  
reboot.  
• 02403 – There was a flaw in the TCP stack buffer which caused the device to  
fail.  
• 02390 – When you created an aggregate interface on a Juniper  
NetScreen-5000 system, a CLI get command and an SNMP get operation  
indicated different bandwidth values for the interface. In some cases, the  
CLI command revealed 100 Mbps and the SNMP command revealed 0 MBps.  
• 02388 – You could not set the DHCP IP address range through the WebUI  
when detecting an auto-probe. By attempting to perform this operation, the  
system displayed the following message:  
The DHCP IP Pool not in the same subnet with gateway/interface  
• 02372 – If you ran an OSPF virtual routing instance on a route-based VPN,  
under heavy traffic conditions, the device could continually spawn new  
sessions for the OSPF packets.

Juniper Networks  
NetScreen Release Notes  
• 02333 – When a device attempted to block files with a .exe extension, it  
incorrectly blocked files with .zip extensions.  
• 02326 – A device incorrectly created sessions if the IP address had a unicast  
destination while the destination MAC address had a multicast destination.  
• 02298 – Commands related to NHTB (Next Hop Tunnel Binding) did not run  
when you used a blank character when creating a tunnel name for NHTB.  
• 02297 – An anti-virus scan dropped connections with selected HTTP and  
HTTPS sites.  
• 02116 – When the lifetime of an IKE Phase 2 SA (Security Association)  
reached a threshold defined by the soft lifetime buffer, a Phase 1 rekey and a  
delete notification for the P2 SA was generated after the P1 rekey.  
• 02026 – When a device attempted to contact a RADIUS server and the  
server was unavailable, the device corrupted the server reply after it was  
stored in device memory.  
• 02024 – When a device contacted a RADIUS server for authentication while  
the server was performing many RADIUS authentications, the device  
corrupted the server reply after it was stored in device memory.  
• 01957 – The WebUI did not contain the ISP connection Test button under  
the Configure column in the ISP screen because a previous revision of  
ScreenOS was released with the button removed. The button now appears in  
this location.  
• 01822 – A Juniper NetScreen-5000 device incorrectly sent packets from an  
inactive VSI (Virtual Security Interface). The device now first considers  
whether a VSI is active before it sends packets from it.  
• 01862 – After upgrading a Juniper NetScreen-5400 to ScreenOS 4.0.1-  
SBR.2a2, the get ip-classification command displayed incorrect data for IP  
classifications currently on the device.  
• 01782 – A hidden command incorrectly dropped an incoming packet to a  
Juniper NetScreen-5000 device when an ARP entry was not present on the  
device. The device now responds properly to an incoming packet when no  
ARP entry is present, placing the packet in a queue of other packets and  
forwarding it after six seconds.  
• 01779 – The Track-IP operation in an Active-Active setup on an HA pair of  
Juniper NetScreen-5000 devices incorrectly selected an outgoing interface in

sessions.  
• 38103 – The DHCP client was unable to obtain an IP address if Dynamic  
Track IP was enabled and the DHCP client interface was down.  
• 37711 – When you have established a VPN tunnel and tried to perform a  
Phase II rekey, the operation intermittently failed.  
• 02449 – The server kept sending LCP requests as if it never received a  
packet because the PPP (Point-to-Point Protocol) request sent out never left  
the device.  
• 02446 – Unfreed memory buffers could be allocated to the point where the  
device could not send management traffic data.  
• 02429 – HTTP packets could not pass through the Juniper NetScreen-5200  
running ScreenOS 4.0.0 if you issue both the unset flow tcp seq and set  
flow tcp syn commands.  
• 02419 – The WebUI label IP Sweep/Port Scan in the IP and Port Scan  
field in the Screen menu contained incorrect references to milliseconds (5000  
ms) instead of microseconds with the ms abbreviation (ms is the  
abbreviation for milliseconds).  
• 02416 – If you rebooted a Juniper NetScreen-5200 after configuring NHTB  
entries in the current session on the system, the device lost the entries after  
the reboot.  
• 02415 – A RIP routing instance dropped the default route (0.0.0.0) of another  
routing instance if it learned it on an unnumbered tunnel interface.  
• 02413 – When you issued the command set ike gateway, the device always  
created a test certificate peer certificate type x509-signature.  
• 02411 – An NSRP Track-IP session on a sub-interface failed in instances  
when the target address and the default route (0.0.0.0) were on the same  
subnet. In these instances, the Track IP query incorrectly selected the  
default route (0.0.0.0).  
• 02387 – The command line displayed only 24 characters for a URL string,  
although ScreenOS supports URL strings with up to 64 characters.

Juniper Networks  
NetScreen Release Notes  
• 02384 – The device failed if you connected an Ethernet cable to the untrust  
interface in the v1-untrust zone while the device was in transparent mode.  
• 02383 – Under some circumstances, the OSPF routing instance could not  
build an adjacency because its memory buffer was not large enough to  
handle large databases.  
• 02379 – You could not establish the Phase II portion of a VPN tunnel when  
you referenced a custom service that had spaces in its name with no quote  
marks around the string because ScreenOS did not recognize strings with  
spaces without quotes around the string.  
• 02377 – The Juniper NetScreen-200 did not always free up memory after  
VPN tunnels closed, requiring a manual device reboot to recover.  
• 02375 – The device was unable to detect and defend against a ping of death  
attack and would fail when these types of packets arrived at the device.  
• 02372 – You could not clear sessions on Juniper NetScreen-50 devices in an  
active-passive environment in instances when the active device stopped  
creating new sessions when the session table was full.  
• 02370 – When you manually created a VPN tunnel in an NSRP environment  
in the WebUI, using an extra comma in the key portion of the set vpn  
command, the primary device failed while the backup device kept the old  
configuration.  
• 02368 – ScreenOS removed the quotation marks around the VPN name with  
a space when you configured an NHTB value on an interface.  
• 02364 – The device generated an unknown keyword error to the keyword all-  
virtual-system when you tried to assign a new admin password to a VSYS.  
• 02354 – Occasionally, the ScreenOS logging environment incorrectly  
displayed unusual logs that indicated a hacker attacked the device. A typical  
message that indicated a hacker was the following:  
2004-02-11 11:45:22 system notif 00001 Address  
_prefix_c0000000_2_p72_ for ip address 192.0.0.0 in zone V1-  
Untrust has been deleted by netscreen via web from host  
128.32.199.217 to 128.32.199.71:80 session  
• 02336 – In an NSRP active-active environment, when the customer  
disconnected all the cables from the HA1, HA2, and MGT interfaces on  
either device, and they reconnected cables to the HA1 and HA2 interfaces,  
the device rebooted.  
• 02323 – When you ran FTP Put or Get commands to push or obtain data to  
or from the device, the WebUI always indicated the device had a Deny action  
in its policy even when the policy was configured to permit traffic.

Juniper Networks  
NetScreen Release Notes  
• 02272 – HTTP and HTTPS packets passed through VPN tunnels more  
slowly than expected, sometimes to the point of timing out and causing the  
device to continually retransmit the packets.  
• 02250 – The device sometimes generated an error when you updated a  
device and issued the following command with the following arguments:  
set interface tunnel.2 nhtb 10.1.2.5 vpn

the device contained more than 15,000 VPN tunnels and received ICMP  
traffic.  
• 02156 – When you enable Scan-MGR, it prevented access to certain web  
pages because during the TCP 3-way handshake, the web server advertised a  
window size of 0 to the client, preventing the web page window from opening.  
• 02094 – The Address Negate feature had no effect on traffic entering the  
device through a VPN tunnel with a VPN tunnel policy applied to it.

Juniper Networks  
NetScreen Release Notes  
• 37069 – The configuration wizard option in the WebUI that enables you to  
skip the wizard screens was not present on the initial wizard screen. This  
option enables you to go directly to the WebUI login window to enter the  
device to manage it.  
• 36669 – When 20,000 or more policies were configured on a Juniper  
Networks security appliance, you experienced a two- to three-minute delay  
when scrolling through the Policy List page in the WebUI.  
• 36939 – The Juniper NetScreen-25 and Juniper NetScreen-50 did not  
support up to eight VLANs as expected and the Juniper NetScreen-20x did  
not support up to 32 VLANs as expected.  
• 02259 – In an Active-Active NSRP configuration, the device did not accept  
traffic that terminated on the device interface in active mode on a different  
zone than the one with the source IP zone.  
• 02211 – The IPSec pass-through operation failed because ScreenOS 5.0.0r3  
required an incoming policy to work properly.  
• 02206 – After the AV waited for HTTP get packets and did not receive them  
after a few seconds, the CSP sent resets to nodes on both sides of the device.  
• 02175 – By performing a policy search (a scan of a policy group to locate a  
specified entry), the device failed because ScreenOS improperly initialized  
policy counters which keep track of policies, and the search improperly  
returned a null pointer.  
• 02160 – When the Anti-Virus scan engine scanned large email messages, the  
device sometimes failed if the amount of time specified by the SMTP scan  
timeout elapsed before the amount of email data scanned exceeded the Max  
Content Size limit.  
• 02156 – When the AV Scan-MGR option enabled in a policy detected a SYN-  
ACK packet associated with a site with a window size of zero, the device  
dropped the packet.  
• 02153 – When trying to establish a GRE tunnel between two PCs with one  
connected to the Trust interface and the other to the Untrust interface, using  
policy-based source NAT, the tunnel failed because a GRE tunnel requires  
fixed source and destination ports and the policy-based source NAT process  
changes the port values.  
• 02148 – The device might fail when Vsys traffic changes to the root sys mod  
when the traffic is en route to a Mapped IP (MIP) object.  
• 02145 – When SMTP traffic entered the device and combined with the SMTP  
rcpt command, it sometimes bypassed the Anti-Virus scanning engine.  
• 02142 – The SSH_MSG_IGNORE message and SSH-1.99- version string  
were not handled by ScreenOS.

Juniper Networks  
NetScreen Release Notes  
• 02134 – When a policy specified a service that contained the same ranges for  
both the source port and destination port, traffic associated with other  
services with the same port ranges matched the conditions of the policy and  
the policy would respond with actions associated with a match occurring.  
• 01981 – You could not set the priority of the modem to any values.  
• 01957 – (NetScreen5XT and 5GT only) The modem TEST button was  
missing in the WebUI.  
• 01907 – Previous releases of ScreenOS 5.0.0 did not support Bootstrap  
Protocol (BootP) requests.  
• 02139 – If you created a session on the device and no other session is active  
on the device, the device still generated a log. Juniper Networks security  
appliances should generate logs only if you create a session on the device and  
at least one other session is active on the device.  
• 02117 – For a uni-directional dialup or site-to-site route-based VPN, specific  
routes were required on the receiving VPN device so that the returning  
traffic could go back into the correct tunnel interfaces accordingly. This was  
a result of the dynamic routing failover feature in ScreenOS 5.0.0.  
• 02106 – After changing the local Auth server timeout in the WebUI from the  
default value of 10 minutes to any other timeout value, you could not reset  
the timeout back to 10 minutes.  
• 02104 – In transparent mode, devices dropped VTP (VLAN Trunking  
Protocol) and Spanning Tree packets.  
• 02095 – The device failed when it performed a custom Deep Inspection  
examination on a signature that contained a string of characters that was  
long enough to cause the device memory buffers to overflow.  
• 02094 – The address negate feature did not work for traffic coming from a  
VPN tunnel policy.  
• 02078 – If the same Auth/L2TP user was defined on both the device and a  
remote Radius server, the device did not release the assigned IP address  
back to the address pool, as expected, after the user disconnected from the  
tunnel connection on the device.  
• 02076 – (Juniper NetScreen-5XP only) The device Status LED light blinked  
with a longer interval between each illumination (more slowly) than it did  
when running ScreenOS 4.0.0.  
• 02072 – Several SNMP Object ID (OID) data types that identify a specific  
vendor were incorrect. Some counters associated with OIDs always returned  
a zero value.  
• 02065 – SNMP traps were improperly formatted with numerical values that  
indicated an incorrect trap type. SNMP maps specific integers to indicate  
specific trap types, or events that generate traps. Because of this

discrepancy, you had to read the text description of the trap type to identify  
it. Now you can refer to the trap type value to identify it. For example, the  
traditional SNMP trap type value for a Cold Start event is 0. Please check  
the ScreenOS Messages Guide for the correct values in ScreenOS 5.0.0.  
• 02062 – Under certain circumstances, Track-IP was not sent out and caused  
the NSRP failover operation to fail.  
• 02059 – When you changed an IKE gateway from Static IP to Dynamic IP  
using the WebUI, the procedure automatically changed the setting from  
Main Mode to Aggressive mode.  
• 02057 – Multiple custom addresses or service groups in a policy sometimes  
caused a Juniper Networks security appliance to fail during restart.  
• 02050 – Configuring an address group from an Apple computer using  
Internet Explorer sometimes caused a Juniper Networks security appliance  
to fail.  
• 02047 – When the device received a packet with Ethernet type 0x8888, the  
device failed.  
• 02045 – Under certain circumstances, the device incorrectly flagged and  
dropped IP-Spoof packets.  
• 02044 – An operation using SSH version 1 to access the device failed when  
using Radius for administration authentication.  
• 02035 – The device did not allow URL filtered traffic when the URL queue  
was full and the URL queue size was too small to process heavy traffic.  
• 02034 – In transparent mode, when selecting the WebAuth option in the  
WebUI for the V1-Untrust Zone, it appeared to take effect, but when closing  
the window and then returning to the V1-Untrust configuration window, the  
WebAuth option was no longer selected.  
• 02019 – You could not use the WebUI to remove the key id and preshared  
key of the primary NTP server.  
• 02018 – The Juniper Networks security appliance failed when applying  
debug commands, for example, the set ffilter command.  
• 02001 – If a dynamically added route and a static route on a device both used  
the same interface default gateway as the next hop, when the dynamic  
route’s interface default gateway changed, the static route’s gateway did not  
change with it as expected.  
• 01993 – You could not modify management services on interfaces configured  
in the WebUI environment to obtain addresses using DHCP.  
• 01986 – In an NSRP environment, the primary device sometimes had more  
active XAuth users than the backup device because the garbage collection  
mechanism for IPSec SA removed XAuth users from the backup device at a  
more accelerated rate than it did from the primary device.

• 01985 – You could not schedule a policy using the WebUI.  
• 01970 – Under certain circumstances, the Juniper Networks security  
appliance did not send email alerts.  
• 01943 – When the DHCP payload (information included with the issuance of  
an IP address from a DHCP server) exceeded 550 bytes in length, the  
Juniper Networks security appliance was unavailable to send packets  
associated with the payload because the DHCP relay mechanism did not  
accept the packets.  
4.7 Addressed Issues from Previous Releases  
This section describes issues addressed in ScreenOS 5.0.0 release prior to  
ScreenOS 5.0.0r4.  
• 37027 – The issue described in security advisory NS#54169 was addressed.  
• 36935 – You could not reset the Juniper Networks security appliance to  
factory defaults settings if the NSRD wizard failed to connect the device to  
the Security Manager server.  
• 36881 – In certain cases, using the pinhole to reset the Juniper Networks  
security appliance to factory default settings failed.  
• 36865 – When a serial interface had no IP address, even if it was in the “UP”  
state, the routing entry pointing to the serial interface stayed inactive.  
• 36838 – A device failure could occur if the interface information derived for a  
non-ip packet and received on a 24FE board is invalid.  
• 36822 – Entering the get policy CLI command sometimes caused the  
Juniper Networks security appliance to reboot.  
• 36819 – Under certain circumstances, IP-Spoof packets were incorrectly  
flagged and dropped.  
• 36814 – With dialup user group VPN manually configured proxy-id, it could  
not be used for bi-directional dial-up vpn policy.  
• 36773 – In Transparent mode, the IP Address Spoof Protection screen option  
caused the Juniper Networks security appliance to incorrectly drop packets  
even if the “Generate Alarms without Dropping Packet” option was enabled.  
• 36766 – (Juniper NetScreen-5GT only) In transparent mode, during the  
initial connection attempt where the device had no established route to the  
destination, initial traffic was dropped on occasion by the device when AV  
scanning was active.  
• 36736 – A device configured with DHCP and via a configlet was unable to  
connect to NSM.

Juniper Networks  
NetScreen Release Notes  
• 36717 – When upgrading to ScreenOS 5.0.0, the maximum number of  
address groups allowed for Layer2 predefined zones incorrectly got set to the  
same number as for custom zones. As a result, if the number of address  
groups in Layer2 predefined zones surpasses the maximum number allowed,  
some address groups got removed during the upgrade.  
• 32690 – (Juniper NetScreen-5GT only) When multiple devices were  
connected with AV scanning enabled on policies, no traffic passed through  
the devices. For example, if two devices were connected together and both  
had AV scanning enabled on policies, no traffic traversed the devices.  
• 02081 – The active user table failed to clear automatically. New users were  
denied until the table was manually cleared.  
• 02079 – In an instance where the system was running in transparent mode,  
when you enabled traffic shaping mode, the system dropped all packets.  
• 02038 – Reboots occurred occasionally when traffic matched policies which  
had authentication enabled.  
• 02027 – An SNMP sysObject OID reply returned in the wrong format.  
• 02006 – Enabling DHCP Relay could cause a Juniper Networks security  
appliance to crash.  
• 01972 – A DHCP relay packet sometimes caused a Juniper Networks  
security appliance to crash.  
• 01971 – You were not able to add physical interfaces (different ports) of a  
Juniper Networks security appliance in the same redundant interface group.  
• 01968 – (Juniper NetScreen-5GT only) Ident-reset packets that terminated  
on the device might have caused the device to restart.

• 01958 – An internal mishandling of the MAC cache could cause a security  
appliance to crash.  
• 01944 – The group addresses for V1-untrust zone were getting lost after  
upgrading a device from a previous release. The group address for v1-untrust  
• 01812 – Using un-initialized memory space when creating an outgoing  
packet caused the device to fail.  
5. Known Issues  
This section describes known issues with the current release.  
Section 5.1 “Limitations of Features in ScreenOS 5.0.0” identifies features  
this release. Juniper recommends that you do not use these features.  
Section 5.2 “Compatibility Issues in ScreenOS 5.0.0 on page 30” describes  
known compatibility issues with other products, including but not limited to  
specific Juniper NetScreen appliances, other versions of ScreenOS, Internet  
browsers, Juniper management software and other vendor devices.  
Whenever possible, information is provided for ways to avoid the issue,  
minimize its impact, or in some manner work around it.  
Section 5.3 “Known Issues in ScreenOS 5.0.0 on page 32” describes  
deviations from intended product behavior as identified by Juniper  
Networks Test Technologies through their verification procedures. Again,  
whenever possible, information is provided to assist the customer in avoiding  
or otherwise working around the issue.  
5.1 Limitations of Features in ScreenOS 5.0.0  
The following limitations are present in ScreenOS 5.0.0.  
• No Support for Packet Attribute Features – The Juniper NetScreen-  
5000 Series systems do not support the aggressive aging, maximum  
fragment size, path MTU (Maximum Transmission Unit), and Interface  
MTU features.  
• Vsys for Group IKE ID – Group IKE ID users cannot be used in a vsys if  
that vsys uses a shared untrust interface.  
W/A: Use a private Untrust interface (tagged VLAN subinterface or  
dedicated physical interface) for the vsys.

Juniper Networks  
NetScreen Release Notes  
• SSH Version 1 Interoperability – The embedded SSH server in ScreenOS  
5.0.0 has issues with the client from SSH Communications Security when  
operating in SSH version 1 mode.  
W/A: Use SSH version 2 or a different SSH version 1 client, such as  
OpenSSH.  
• Primary & Backup Interfaces – (Juniper NetScreen-5XT) The primary  
and backup interfaces bound to the Untrust security zone cannot both use  
DHCP for address assignment at the same time. You can use DHCP for one  
interface and PPPoE for the other. Or you can use PPPoE for both interfaces.  
• Loading License Keys – The Juniper NetScreen-5XP device does not  
properly load license keys via the WebUI. However, you can load license keys  
via the CLI using the exec license-key command.  
• Aggressive Aging – The Aggressive Aging feature is not supported on the  
Juniper NetScreen-5000 Series devices.  
• SSHv2 Implementations – The SSHv2 feature specification requires  
support for two implementations: OpenSSH and Secure CRT.  
• Upgrade Limitations – When upgrading a device to ScreenOS 5.0.0UPGR  
in Transparent mode, the device experiences the following problems:  
– The device fails during upgrading from ScreenOS 4.0.1 to ScreenOS 5.0.0  
in a VPN scenario.  
– In clear text situations (where traffic is not encrypted to pass through a  
VPN tunnel), after the upgrade to ScreenOS 5.0.0UPGR, the user had to  
run the clear arp and clear mac-l commands to enable the device to  
work because some ARP entries learn on the wrong port.  
• Updated Message ID Numbers – The NetScreen Message Log Reference  
Guide (Part Number 093-0917-000 Rev. D) now contains an updated  
message ID number for Deep Inspection attack messages. The message,  
formerly associated with ID number 00001, now maps to ID number 00601.  
Although the ID number has already been changed in the guide, the ID  
number will not change in the code until the next revision of ScreenOS 5.0.0.  
5.2 Compatibility Issues in ScreenOS 5.0.0  
Below are the known compatibility issues at the time of this release. Whenever  
possible, a workaround (starting with “W/A:”) has been provided for your  
convenience.

Juniper Networks  
NetScreen Release Notes  
Freeswan - The Freeswan 1.3 VPN client is incompatible with ScreenOS  
5.0.0 in certain configurations due to IKE features that Freeswan does not  
fully support. The result is that Phase 2 negotiations and Phase 2 SA will  
not complete if the following commands are enabled in 5.0.0:  
set ike initiator-set-commit  
set ike responder-set-commit  
set ike initial-contact  
W/A: Unset these commands to ensure compatible configuration on the  
Juniper Networks security appliance.  
• Compatible Web Browsers - The WebUI for ScreenOS 5.0.0 was tested  
with and supports Microsoft Internet Explorer (IE) browser versions 5.5 and  
above, and Netscape Navigator 6.X for Microsoft Windows platforms, and  
Microsoft Internet Explorer version 5.1 for MacOS 10.x. Other versions of  
these and other browsers, were reported to display erroneous behavior.  
• SNMP Trap Type Values Different in ScreenOS 5.0.0 – ScreenOS 5.0.0  
uses a different numbering system than previous ScreenOS releases to  
identify trap types. SNMP maps specific integers to indicate specific trap  
types, or events that generate traps. For example, the traditional SNMP trap  
type value for a Cold Start is 0. However, different vendors deploy different  
values to indicate different trap types. Please check the ScreenOS Messages  
Guide for the correct values in ScreenOS 5.0.0.  
5.2.1 Upgrade Paths from Previous Releases  
For detailed information on how to upgrade any Juniper Networks security  
appliance from ScreenOS 4.0.0 and later to ScreenOS 5.0.0, refer to the  
NetScreen ScreenOS Migration Guide. The migration guide provides step-by-  
step upgrade procedures and important information about upgrading  
Juniper Networks security appliances.  
Important: To avoid downtime while upgrading devices in an NSRP  
configuration (active-passive or active/active), refer to the NetScreen  
ScreenOS Migration Guide which describes procedures to upgrade the devices  
without causing any downtime.  
The migration guide also provides a step-by-step procedure to downgrade a  
Juniper Networks security appliance from ScreenOS 5.0.0 to ScreenOS 4.0.0  
and later using the exec downgrade CLI command.

Juniper Networks  
NetScreen Release Notes  
Juniper NetScreen-5000 series only: Before you upgrade a Juniper  
Networks security appliance to ScreenOS 5.0.0, we recommend that you  
verify the amount of memory on the device using the get system CLI  
command. You need 1 gigabyte of memory for Juniper NetScreen-5000. If  
you start upgrading the device and run into memory problems, you might see  
the following messages: “insufficient memory, call TAC” or “see release notes  
for upgrade instructions”.  
To avoid network downtime while upgrading devices in an NSRP  
configuration, refer to the Upgrading Devices in an NSRP Configuration  
without Downtime document. You can download this document from the  
location on the CSO where the revision image resides.  
NSM does not support the NSRP Configuration without Downtime feature.  
5.3 Known Issues in ScreenOS 5.0.0  
The following are known deficiencies in features at the time of this release. Whenever  
possible, a work-around is suggested following the description of the problem.  
Workaround information starts with “W/A:” If there is no subsection for a particular  
ScreenOS release, no new known issues were identified for that release.  
5.3.1 Known Issues in ScreenOS 5.0.0r9-FIPS  
• 04960 – A burst of logs sent from a device running ScreenOS to the Security  
Manager server sometimes creates memory corruption, causing the device to  
fail.  
• 03773 – The device drops some IPSec AH packets because of authentication  
failures, slowing the transfer of packets over an FTP session and sometimes  
causing large FTP data transfer sessions to fail.

incorrectly displays as more than 497 days.  
• 03495 – When the device drops packets after you issued the set flow tcp-  
syn-check command, ScreenOS does not log the drop instances.  
• 03492 – When you enable the URL filtering service, the device drops HTTP  
Move packets.  
• 03484 – If an interface rapidly repeatedly disconnects and reconnects, the  
number of OSPF routes drops below the number of expected routes causing  
the OSPF routing instance to clear its route table.  
• 02751 – After resubmitting the ICMP destination unreachable setting  
through the device, the packet passes through the device, but the device  
generates the following log message:

different than the correct date.  
• 02927 – Devices upload HTTP traffic very slowly after you enable both the  
anti-virus and URL filtering options in a policy on the device.  
• 02869 – A Juniper NetScreen-5GT cannot deliver mail and the POP3 (Post  
Office Protocol 3) session times out when the device runs an anti-virus scan  
on an SMTP or POP3 policy.  
• 02297 – An anti-virus scan drops connections with selected HTTP and  
HTTPS sites.  
• 02266 – When you make one configuration change on a device, the device  
sometimes sends out more than one entry associated with that change to  
both the syslog and WebTrends servers.

None.  
5.3.4 Known Issues from ScreenOS 5.0.0r6  
None.  
5.3.5 Known Issues from ScreenOS 5.0.0r5  
None.  
5.3.6 Known Issues from ScreenOS 5.0.0r4  
• 38109 – When running 5,000 UDP sessions between two non-ScreenOS 5.0.0  
devices and you upgrade one device to ScreenOS 5.0.0UPGR and the other to  
ScreenOS 5.0.0r4 via ScreenOS 5.0.0UPGR, only 3,000 of the UDP sessions  
synchronize properly.  
• 37938 – The Juniper NetScreen-5000 or Juniper NetScreen-500 device  
sometimes fails after upgrading from an older version of ScreenOS to  
ScreenOS 5.0.0UPGR.  
• 37925 – The L2TP tunnel and Telnet utility both do not work on the Juniper  
NetScreen-5000 or Juniper NetScreen-500 device after you upgrade the  
device from ScreenOS 4.0.1r4.2 to ScreenOS 5.0.0UPGR.  
• 37901 – After you upgrade a Juniper NetScreen-5000 or Juniper NetScreen-  
500 device from a running ScreenOS 5.0.0UPGR B (backup) to ScreenOS  
5.0.0UPGR M (primary), the current session on the device disappears.  
• 02369 –You could not change the IKE/AUTH user password using the  
WebUI. The WebUI apparently takes the change but it does NOT change it  
when the configuration is viewed.  
• 02297 – The Anti-Virus scanning engine drops connection with some HTTP/  
HTTPS sites.  
• 02207 – The NS Lookup operation completes without first authenticating to

5.3.7 Known Issues from ScreenOS 5.0.0r3 for the 5000-M2  
• 38001 – When you run the get session command, ScreenOS sometimes  
displays the policy ID number incorrectly as a negative number.  
• 37993 – When enabled on a Juniper NetScreen-5000 Series system, the  
inter-zone IP record route option does not update the counter associated with  
this option. The record route option records the IP addresses of the network  
devices along the path that an IP packet travels. The destination device then  
can extract and process the route information.  
• 37974 – When attack packets associated with the syn-and-fin, block-  
fragment, and unknown-protocol events attempt to enter a Juniper  
NetScreen-5000 Series system using a 5000-24FE secure port module when  
the system experiences heavy traffic, the system ASIC may not be able to  
transmit packets from the device. A syn-and-fin attack is an instance where  
a TCP header contains both syn and fin flags set. A block-fragment event is  
when the NetScreen system attempts to deny entry of fragments of a larger  
packet that have been disassembled so they may enter the device with  
undetected attack content. An unknown-protocol attack is a packet that  
contains a protocol that the NetScreen system does not recognize.  
• 37712 – You cannot remove an SSH key from a Vsys by running the  
command unset ssh pka all. When you run the command, ScreenOS does  
not remove the SSH key and displays a generic error message.  
• 37640 – You can create a password name with a greater number of  
characters than the usual character limit (15) for passwords in ScreenOS for  
the Juniper NetScreen-5000 Series systems.  
• 37497 – You could not create more than 1,500 IKE sessions (attempting to  
establish VPN tunnels) while the system experienced heavy traffic.  
• 37422 – When you loaded an older ScreenOS configuration image on a new  
Juniper NetScreen-5000 Series system, the system failed. If the system now  
functions correctly, remaining active with ScreenOS displaying an error  
message on the console indicating a mismatch between the loaded image and  
the image(s) the system accepts.  
• 37303 – You can create an environment variable with a greater number of  
characters than the usual character limit (255) for environment variable  
strings in ScreenOS for the Juniper NetScreen-5000 Series systems.

• 36807, 36876 – When a 100Mbps link between a Juniper NetScreen-5000  
Series system and another device reverts to a 10Mbps throughput level on  
the other device, the Juniper NetScreen-5000 Series system remains at the  
100Mbps throughput level when it should synchronize with the speed of the  
connected device and revert to the lesser speed.  
5.3.8 Known Issues from ScreenOS 5.0.0r3  
None.  
5.3.9 Known Issues from ScreenOS 5.0.0r2  
• 35620 - (Juniper NetScreen-5GT only) If a policy is using a local address, any  
modification to the netmask of the address produces a trace dump on the  
console. This modification should not be a permitted action for the device.  
• 36365 - In the WebUI, on the Traffic Log page for policies (under Reports),  
the table displaying the information might disappear after viewing multiple  
pages of traffic logs.  
W/A: Refresh the Traffic Log page for policies by clicking the Refresh button  
on your Internet Browser.  
5.3.10Known Issues from ScreenOS 5.0.0r1  
• Documentation Correction - Page 3 of the What's New in NetScreen  
ScreenOS 5.0 states incorrectly that Juniper Networks security appliances  
support routing based on the source interface. The current implementation  
does support routing based on source IP address.  
• 36018 - (Juniper NetScreen-5GT only) The two month entitlement  
expiration notice in the event log is triggering during the incorrect  
timeframe. For example, if the AV entitlement expires in 52 day, the event  
log indicates "License key av_key is about to expire in 2 months".  
• 35582 - In an NSRP configuration, active/active or active-passive, if you  
move a physical interface to a different zone on one device, you must  
manually do the same on the other device because this type of change does  
not get automatically synchronized.  
• 35516 - In an active-passive NSRP configuration, when you load a PKA key  
onto the master device, the master does not automatically synchronize the  
backup device.  
W/A: Manually synchronize the two devices.  
• 35439 - (Juniper NetScreen-5GT only) Within the WebUI, identical routes  
are displayed on multiple pages. When the number of routing table entries

NetScreen Release Notes  
exceeds the maximum number of routes permitted on a single page, all  
subsequent pages display the routes from the first page.  
• 35417 - If you set the guaranteed or maximum bandwidth (GBW or MBW)  
higher than the interface bandwidth, traffic does not pass through if there is  
a policy configured that specifies traffic shaping.  
W/A: Adjust the GBW or MBW to be equal or less than the interface  
bandwidth.  
• 35336 - If you enabled VPN tunneling for syslog traffic and the source  
interface is bound to a zone that contains multiple interfaces, after  
upgrading a device from ScreenOS 4.0.0 to ScreenOS 5.0.0, the source  
interface might have changed.  
W/A: After upgrading the Juniper Networks security appliance, verify the  
VPN settings for syslog and modify if necessary.  
• 35238 - For devices in an NSRP configuration, active/active or active-  
passive, you have to manually issue the delete ssh device all CLI  
command on both devices.  
• 34950 - (Juniper NetScreen-5000 only) Failover between two layer 2  
interfaces in the same layer 2 security zone is not supported.  
• 34922 - (Juniper NetScreen-50 only) You cannot configure a VSI when the  
Juniper Networks security appliance is in an active-passive NSRP  
configuration.  
• 34880 - (Juniper NetScreen-5GT only) Issuing the CLI command 'set  
interface <interface> manage ident-reset' displays incorrectly as 'set  
interface <interface> ident-reset' (without the word "manage" in the  
configuration file).  
• 34670 - (Juniper NetScreen-5GT only) Issuing the CLI command 'set/unset  
firewall exclude log-self exclude ike' does not change the state of "Log Self for  
IKE". The 'get firewall' command displays "Log Self for IKE" constantly in  
the "Off" state.  
• 34663 - Enabling the RTO mirror group direction feature using the set nsrp  
rto-mirror id <id> direction { in | out } CLI command, might cause the  
preempt mode feature not to work.  
• 34414 - The Juniper Networks security appliance does not perform a  
revocation check on the signature attack database upon requesting an  
update.  
• 34070 - (Juniper NetScreen-5GT only) The event message 'AV: Suspicious  
client <Source IP> <Source Port> -> <Destination IP> <Destination Port>  
used <X> percent of AV resources, and exceeded the max. of <y> percent'

issue a 'get log event' CLI command.  
• 33916 - A Juniper Networks security appliance supports a maximum of 256  
OSPF interfaces.  
• 33598 - For inter-vsys traffic, if both vsys define a policy with user  
authentication, the Juniper Networks security appliance does not prompt  
the user for authentication for each policy, but only once when it matches the  
first policy.  
• 33544 - Normally upon startup, a Juniper Networks security appliance with  
the URL filtering feature enabled, tries to connect to a Websense server.  
Currently this attempt to connect to a Websense server fails and the Juniper  
Networks security appliance logs the event.  
• 33027 - Juniper Networks security appliances do not support policy-based  
dialup VPN and MIP if the MIP is configured on the tunnel interface which  
belongs to a tunnel zone.  
W/A: For dialup user VPNs only: use routing-based VPN and configure the  
MIP on a tunnel interface bound to a security zone.  
• 32983 - You can select multiple services in a policy, but later on, if you want  
to modify the services to ANY, the Juniper Networks security appliance does  
not let you. Instead, you get a message prompting you to use the multiple  
service selection dialog box, which does not contain ANY, to modify the  
services.  
W/A: In the multiple service selection dialog box, remove all but one service  
from the previous selection, and then click OK. Next, select “ANY” from the  
Service drop-down list.  
• 32159 - Juniper Networks security appliances do not support a second level  
of certificate verification if the end entity certificate and OCSP responder  
certificate are issued by the same CA.

Webmail functionality, log entries are not generated in the event log (i.e. 'set/  
unset av http webmail enable'; 'set/unset av http webmail url-pattern-name  
<name for the URL pattern>').  
• 32072 - (Juniper NetScreen-5GT only) When you disable AV functionality for  
HTTP, SMTP, and POP3, log entries are not generated in the event log (i.e.  
'unset av scan-mgr content http'; 'unset av scan-mgr content smtp'; 'unset av  
scan-mgr content pop3').  
• 31364 - When performing source port translation for passive FTP data  
channel, the Juniper Networks security appliance translates the source port

number to the same port number as the original destination port. This does  
not affect traffic.  
• 30844 - When AV is enabled, you cannot download files to the Juniper  
Networks security appliance through a VPN using the WebUI.  
W/A: Specify a permit policy and place it above the policy with AV in the  
policy list.  
• 30842 - Source and destination NAT are not supported for RTP and RTCP  
traffic for H.323.  
• 28878 - Removing a vsys does not free the memory (30 bytes) used by that
