Billion 800VGT Router
Chapter 1: Introduction
Introduction to your Router
Your Billion 800VGT router is an “all-in-one” ADSL VoIP router, combining an ADSL 2/2+
modem/router, network switch and 2 telephone ports for Voice over IP functionality, providing everything
you need to get you connected to the Internet using your ADSL connection.
Features
Voice over IP Compliance with SIP Standard
This router supports cost-effective, toll-quality voice calls over the Internet. It complies with the most
popular industrial standard, SIP protocol, to ensure the interoperability with SIP devices and major
VoIP Gateways. This router supports call waiting, silence suppression, voice activity detection
(VAD), comfort noise generation (CNG), line echo cancellation & caller ID (Bell 202, V3).
Fixed-Line Support
The router integrates RJ-11 FXO port for inbound and outbound calls transmitted through PSTN.
Users can receive phone calls from PSTN while enjoying VoIP call service at the same time. In
addition, the device has automatic fallback to the POTS line to enable making normal phone calls
when there is a power outage, or when the Internet connection is down (lifeline function).
Express Internet Access
This router complies with ADSL worldwide standards. It supports downstream rate up to 12/24
Mbps with ADSL2/2+, 8Mbps with ADSL. Users can enjoy not only high-speed ADSL services but
also broadband multimedia applications such as interactive gaming, video streaming and real-time
audio. It is compliant with Multi-Mode standard (ANSI T1.413, Issue 2; G.dmt (ITU G.992.1);
G.lite (ITU G.992.2); G.hs (ITU G994.1); G.dmt.bis (ITU G.992.3); G.dmt.bis.plus (ITU G.992.5)).
Virtual Private Network (VPN)
This function allows user to make a tunnel with a remote site directly to secure the data
transmission among the connection. Users can use the embedded PPTP, IPSec or L2TP
client/server, which are supported by this router to make a VPN connection.
802.11g Wireless AP with WPA Support
With the integrated 802.11g Wireless Access Point, the router offers quick and easy access
between the wired network, wireless network and ADSL connection with single device simplicity,
and as a result, mobility to the users. The wireless AP supports 54 Mbps 802.11g data connections,
and is backward compatible with existing 802.11b equipment. The Wireless Protected Access
(WPA1 and WPA2) and Wireless Encryption Protocol (WEP) features enhance wireless security
and provide access control..
Fast Ethernet Switch
A 4-port 10/100Mbps fast Ethernet switch is built in with automatic switching between MDI and
MDI-X for 10Base-T and 100Base-TX ports. An Ethernet straight or crossover cable can be used
directly for auto detection.
Multi-Protocol to Establish a Connection
This router supports PPPoA, RFC 1483 encapsulation over ATM (bridged or routed), PPP over
Ethernet and IPoA to establish a connection with the ISP. It also supports VC-based and
LLC-based multiplexing. Furthermore the device supports multiple PPPoE connections on the
same PVC to allow for smart traffic separation.
Quick Installation Wizard
The router can be setup and managed by using the easy setup wizard software included on the CD
or the GUI (Graphical User Interface) imbedded on the router accessed using the router’s LAN IP
address and a standard web-browser application like Internet Explorer.

Chapter 1: Introduction
Billion 800VGT Router
Universal Plug and Play (UPnP)
This protocol is used to enable simple and robust connectivity among stand-alone devices and
computers from many different vendors. It makes networking simple and affordable for users. UPnP
architecture leverages TCP/IP and the Web to enable seamless proximity networking in addition to
control and data transfer among networked devices. With this feature enabled, users can now
connect to applications such as Net Meeting or MSN Messenger seamlessly.
Network Address Translation (NAT)
This function allows multiple users to access outside resources such as the Internet
simultaneously with one IP address/one Internet access account. Many application layer
gateways (ALG) are supported, such as web browsing, ICQ, FTP, Telnet, E-mail, News,
Net2phone, Ping, NetMeeting,
IP phone and others.
SOHO Firewall Security with DoS and SPI
Along with the built-in NAT natural firewall feature, the router also provides advanced hacker
pattern-filtering protection. It can automatically detect and block Denial of Service (DoS) attacks.
The router is built with Stateful Packet Inspection (SPI) to determine if a data packet is allowed
through the firewall to the LAN.
Domain Name System (DNS) Relay
This provides an easy way to map the domain name (a friendly name for users such as
www.yahoo.com) to an IP address. When a local computer has its DNS server IP address
configured to the router’s IP address, every DNS conversion request packet from the Computer to
this router will be forwarded to the real DNS in the outside network.
Dynamic Domain Name System (DDNS)
The Dynamic DNS service allows you to alias a dynamic WAN IP address to a static hostname.
To use the service, you must first apply for an account from a DDNS service like
http://www.dyndns.org/. More than 5 different DDNS services are supported.
Quality of Service (QoS)
QoS gives you full control over which types of outgoing data traffic should be given priority by
the router, ensuring important data like gaming packets, customer information, or management
information move through the router at lightning speed, even under heavy load. The QoS features
are configurable by source IP address, destination IP address, protocol, or port. You can throttle
the speed at which different types of outgoing data pass through the router, to ensure P2P users
don’t saturate upload bandwidth, or office browsing doesn’t bring client web serving to a halt. In
addition, or alternatively, you can simply change the priority of different types of upload data and
let the router sort out the actual speeds.
Virtual Server (“port forwarding”)
Users can specify some services to be visible from outside users. The router can detect incoming
service requests and forward either a single port or a range of ports to the specific local computer to
handle it. For example, a user can assign a PC in the LAN to act as a WEB server and expose it to
Internet users. Outside users can browse this web server directly, while it is still protected by NAT. A
DMZ host setting is also provided to completely expose a local computer the Internet.
Rich Packet Filtering
This not only filters the packet based on IP address, but also based on Port numbers. It will filter
packets to and from the Internet, and provides a higher level of security control.

Chapter 1: Introduction
Billion 800VGT Router
Dynamic Host Configuration Protocol (DHCP) Client and Server
On the WAN interface, the DHCP client can get an IP address from the Internet Service Provider
(ISP) automatically. On the LAN interface, the DHCP server can allocate a range of client IP
addresses and distribute them, including IP address, subnet mask as well as DNS IP address, to
local computers. This provides an easy way to manage the local IP network.
Static and RIP1/2 Routing
It has routing capability and supports a static routing table or RIP1/2 routing protocol.
Simple Network Management Protocol (SNMP)
This is an easy way to remotely manage the router via SNMP.
Web based GUI
The routers’ web based GUI is used for configuration and management. It is user-friendly and
comes with on-line help. It also supports remote management capability for remote users to
configure and manage the router. .
Firmware Upgradeable
This router can be upgraded to the latest firmware through the WEB based GUI.
Rich Management Interfaces
This router supports flexible management interfaces using a local console, LAN or WAN port. Users
can use terminal applications through the console port to configure and manage the device, or
Telnet, WEB GUI, and SNMP through LAN or WAN ports to configure and manage the device. TR-
069 management is also supported, but is normally implemented by a Telkom or your ISP.

Cabling
One of the most common causes of ADSL problems is bad cabling or ADSL lines. Make sure that all
devices connected to your telephone line are turned on, and that all telephones used on the line are
connected via micro filters. On the front of the product is a bank of LEDs. Once you have installed you
router, verify that the LAN Link and ADSL line LEDs are lit. If they are not, check that you are using the
proper/functional cables.
Ensure that all other devices connected to the same telephone line as your router (e.g. telephones, fax
machines, analogue modems) have a line filter connected between them and the wall socket, and ensure
that all line filters are correctly installed and the right way around. Missing line filters or line filters installed
the wrong way around can cause problems with your ADSL connection, including causing frequent
disconnections.

Chapter 3: Basic Installation
The router can be configured with your web browser. A web browser is included as a standard application
in the following operating systems: Linux, Mac OS, Windows 98/NT/2000/XP/Me, etc. The product
provides an easy and user-friendly interface for configuration.
Please check your Computer’s network components. The TCP/IP protocol stack and Ethernet network
adapter must be installed. If not, please refer to your operating system manuals.
You can connect your computer to the router either through an external hub/switch or directly. However,
please ensure that your computer has a properly installed Ethernet interface prior to connecting it to the
router. You ought to configure your Computers to obtain an IP address through a DHCP server or you can
set them up with a fixed IP address that must be in the same subnet as the router. The default IP address
of the router is 10.0.0.2 and the subnet mask is 255.255.255.0 (i.e. any attached Computer must be in the
same subnet, and have an IP address in the range of 10.0.0.1 to10.0.0.254). The best and easiest way is
to configure the PC to get an IP address automatically from the router using DHCP. If you encounter any
problem accessing the router’s web interface it may also be advisable to temporarily remove any kind of
software firewall on your Computer’s as they can cause problems accessing the 10.0.0.2 IP address of
the router. Users should always make their own decisions on how to best protect their network.
Please follow the steps below for your PC’s network environment installation.
Any TCP/IP capable workstation can be used to communicate with
or through the router. To configure other types of workstations,
please consult the manufacturer’s documentation.

WEP Encryption: To prevent unauthorized wireless stations from accessing data transmitted over the
network, the router offers highly secure data encryption, known as WEP. If you require high security for
transmissions, there are two alternatives to select from: WEP 64 and WEP 128. WEP 128 will offer
increased security over WEP 64.
Passphrase: This is used to generate WEP keys automatically based upon the input string and a
pre-defined algorithm in WEP64 or WEP128. Default Used WEP Key: Select the encryption key ID;
please refer to Key (1~4) below.
Key (1-4): Enter the key to encrypt wireless data. To allow encrypted data transmission, the WEP
Encryption Key values on all wireless stations must be the same as the router. There are four keys for
your selection. The input format is in HEX style, 5 and 13 HEX codes are required for WEP64 and
WEP128 respectively, the separator is “-“. For example, using WEP64, 11-22-33-44-55 is a valid key,

Port Setting
This section allows you to configure the settings for the router’s Ethernet ports to solve some of the
compatibility problems that may be encountered while connecting to the Internet, as well as allowing
users to tweak the performance of their network.
Port # Connection Type: this is where you can customize the connection type of each of the
routers Ethernet ports. There are Six options to choose from: Auto, disable, 10M half-duplex, 10M
full-duplex, 100M half-duplex, 100M full-duplex and Disable. Sometimes, there are Ethernet compatibility
problems with legacy Ethernet devices, and you can configure a particular Ethernet port to one of the
different types to solve compatibility issues. The default is Auto, which users should keep unless there
are specific problems with computers not being able to access your LAN.
IPv4 TOS priority Control (Advanced users): TOS, Type of Services, is the 2nd octet of an IP packet.
Bits 6-7 of this octet are reserved and bit 0-5 are used to specify the priority of the packet.
This feature uses bits 0-5 to classify the packet’s priority. If the packet is high priority, it will flow first and
will not be constrained by the Rate Limit. Therefore, when this feature is enabled, the router’s Ethernet
switch will check the 2nd octet of each IP packet. If the value in the TOS field matches the checked values
in the table (0 to 63), this packet will be treated as high priority.

DHCP Server
You can disable or enable the DHCP (Dynamic Host Configuration Protocol) server or enable the router’s
DHCP relay functions. The DHCP protocol allows your router to dynamically assign IP addresses to
computers on your network if they are configured to obtain IP addresses automatically.
To disable the router’s DHCP Server, check Disabled and click Next, then click Apply. When the DHCP
Server is disabled you will need to manually assign a fixed IP address to each Computer on your network,
and set the default gateway for each computer to the IP address of the router (by default this is 10.0.0.2).
To configure the router’s DHCP Server, check DHCP Server and click Next. You can then configure
parameters of the DHCP Server including the IP pool (starting IP address and ending IP address to be
allocated to Computers on your network), lease time for each assigned IP address (the period of time the
IP address assigned will be valid), DNS IP address and the gateway IP address. These details are sent to
the DHCP client (i.e. your PC) when it requests an IP address from the DHCP server. Click Apply to
enable this function. If you check “Use Router as a DNS Server”, the ADSL Router will perform the
domain name lookup, find the IP address from the outside network automatically and forward it back to
the requesting PC in your LAN (your Local Area Network).
If you check DHCP Relay Agent and click Next, then you will have to enter the IP address of the DHCP
server which will assign an IP address back to the DHCP client on your LAN. Use this function only if
advised to do so by your network administrator or ISP.

PPPoE (multisession)
PPPoE multisession allows the user to create multiple PPPoE sessions using a single PVC, using the
exact same principles as normal PPPoE as described above.
PPPoE with Pass-through Connections
PPPoE with pass-through adopts the following method: PPPoE Routed mode + 1483 Bridge Mode. With
pure PPPoE connection, the router can get one WAN address for the router. With the PPPoE and
PPPoE pass-through, concurrently, it allows users to have a WAN address assigned to the router but also
able to get another WAN IP from their ISP using PPPoE dialler (e.g. WinPoETor Windows XP
PPPoE Dialler) at the same time.

DNS
A Domain Name System (DNS) contains a mapping table for mapping between Domain Names and IP
addresses. On the Internet, every host has a unique and user-friendly name (domain name) such as
www.helloworld.com as well as an IP address. An IP address is a 32-bit number in the form of
xxx.xxx.xxx.xxx, for example 10.0.0.2. You can think of an IP address as a telephone number for devices
on the Internet, and the DNS will allow you to find the telephone number for any particular domain name.
As an IP Address is hard to remember, the DNS converts the friendly name into its equivalent IP Address.
You can obtain a Domain Name System (DNS) IP address automatically if your ISP provides it when you
logon. To use this automatically supplied DNS check the Enable box. Usually when you choose PPPoE or
PPPoA as your WAN - ISP protocol, the ISP will provide the DNS IP address automatically. You may leave
the configuration field blank.
Alternatively, your ISP may provide you with an IP address of their DNS. If this is the case, you must enter
the DNS IP address manually.
If you choose one of the other three protocols ─ RFC1483 Routed/Bridged or IPoA, please check with
your ISP as it may provide you with an IP address for their DNS server. You will need to enter the DNS IP
address if you set the DNS of your PC to the LAN IP address of this router.

System
Here are the items within the System section: Time Zone, Remote Access, Firmware Upgrade,
Backup/Restore, Restart and User Management.
Time Zone
This router does not have a real time clock on board; instead, it uses the Simple Network Time Protocol
(SNTP) to get the current time from an SNTP server outside your network. Choose your local time zone,
click Enable and click the Apply button. After asuccessful connection to the Internet, the router will retrieve
the correct local time from the SNTP server you have specified. If you prefer to specify an SNTP server
other than those in the list, simply enter its IP address as shown above. Your ISP may provide an SNTP
server for you to use.
Daylight Saving is also known as Summer Time Period. Many places in the world adopt this during
summer time to move one hour of daylight from morning to the evening in local standard time. Check
Automatic box to automatically set your local time.
Resync Period (in minutes) is the periodic interval the router will wait before it re-synchronizes the
router’s time with that of the specified SNTP server. In order to avoid unnecessarily increasing the load on
your specified SNTP server you should keep the poll interval as high as possible – at the absolute
minimum every few hours or even days.

Remote Access
To temporarily permit remote administration of the router (i.e. from outside your LAN), select a time period
the router will permit remote access for and click Enable. You may change other configuration options for
the web administration interface using Device Management options in the Advanced section of the GUI.
If you wish to permanently enable remote access, choose a time period of
0
minute.
Firmware Upgrade
Your router’s “firmware” is the software that allows it to operate and provides all its functionality. Think of
your router as a dedicated computer, and the firmware as the software it runs. Over time this software
may be improved and modified. Your router allows you to upgrade the software it runs to take advantage
of these changes.
Clicking on Browse will allow you to select the new firmware image file you have downloaded to your PC.
Once the correct file is selected, click Upgrade to update the firmware in your router.
DO NOT power down the router or interrupt the firmware upgrading while
it is still in process. Improper operation could damage the router.

Backup / Restore
These functions allow you to save and backup your router’s current settings to a file on your Computer, or to
restore a previously saved backup. This is useful if you wish to experiment with different settings,
knowing that you have a backup handy in the case of any mistakes. It is advisable to backup your router’s
settings before making any significant changes to your router’s configuration, as well as before
performing a firmware upgrade.
Press Backup to select where on your local computer to save the settings file. You may also change the
name of the file when saving if you wish to keep multiple backups.
Press Browse to select a file from your computer to restore. You should only restore settings files that
have been generated by the Backup function, and that were created when using the current version of
the router’s firmware. Settings files saved to your computer should not be manually edited in any
way.
After selecting the settings file you wish to use, pressing Restore will load those settings into the router.
Restart Router
Click Restart with option Current Settings to reboot your router (and restore your last saved
configuration).
If you wish to restart the router using the factory default settings (for example, after a firmware upgrade or
if you have saved an incorrect configuration), select Factory Default Settings to reset to factory default
settings.
You may also reset your router to factory settings by holding the small RESET pinhole button on the back
of your router in for more than 6 seconds whilst the router is turned on, and then power cycling your
router.

Firewall and Access Control
Your router includes a full SPI (Stateful Packet Inspection) firewall for controlling Internet access from
your LAN, as well as helping to prevent attacks from hackers. In addition to this, when using NAT, the
router acts as a “natural” Internet firewall, as all PCs on your LAN will use private IP addresses that
cannot be directly accessed from the Internet.
Firewall: Prevents access from outside your network. The router provides three levels of security
support:
NAT natural firewall: This masks LAN users’ IP addresses making them invisible to outside users on the
Internet, thus making it much more difficult for a hacker to target any machine on your network. This
natural firewall is on when NAT function is enabled.
When using the Virtual Servers function, your PCs will be exposed to the
degree specified in your Virtual Server settings, provided that the ports
specified are opened in your firewall packet filter settings.
Firewall Security and Policy (General Settings): Inbound direction of Packet Filter rules to prevent
unauthorized WAN computers or applications accessing your local network from the Internet.
Intrusion Detection: Enable Intrusion Detection to detect, prevent and log malicious attacks.
Access Control: Prevents access from computers on your local network:
Firewall Security and Policy (General Settings): Outbound direction of Packet Filter rules to prevent
unauthorized LAN computers or applications accessing the Internet.
URL Filter: Blocks computers on your local network from unwanted websites.
Here are the items within the Firewall section: General Settings, Packet Filter, Intrusion Detection,
URL Filter, IM/P2P Blocking and Firewall Log.

General Settings
You can choose not to enable the Firewall and still have access to URL Filter and IM/P2P Blocking, or you
can enable the Firewall using preset filter rules and modify the port filter rules as required. The Packet
Filter is used to filter packets based-on Applications (Port) or IP addresses.
There are four options when you enable the Firewall, they are:
ꢂAll blocked/User-defined: No pre-defined port or address filter rules by default, meaning that all
inbound (Internet to LAN) and outbound (LAN to Internet) packets will be blocked. Users have to add
their own filter rules for further access to the Internet.
ꢂHigh/Medium/Low security level: The predefined port filter rules for High, Medium and Low
security are displayed in Port Filters of Packet Filter.
Select either High, Medium or Low security level to enable the Firewall. The only difference between
these three security levels is the preset port filter rules in the Packet Filter. Firewall functionality is the
same for all levels; it is only the list of preset port filters that changes between each setting. For more
detailed on level of preset port filter information, refer to Table 1: Predefined Port Filter
.
If you choose one of the preset security levels and add custom filters, this level of filter rules will be saved
and you do not need to re-configure the rules again if you disable or switch to other firewall level.
The “Block WAN Request” is a stand-alone function and not related to whether security is enabled or
disabled. Mostly this is used to preventing a hacker on the WAN from using any scan tools..
Attempting to perform this action remotely may result in blocking of all
access to configuration and management of the device from the Internet.
Use this with caution when connecting over the WAN

Intrusion Detection
The router’s Intrusion Detection System (IDS) is used to detect hacker attacks and intrusion attempts
from the Internet. If the IDS function of the firewall is enabled, inbound packets are filtered and blocked
depending on whether they are detected as possible hacker attacks, intrusion attempts or other
connections that the router determines to be suspicious.
Blacklist: If the router detects a possible attack, the source IP or destination IP address will be added to
the Blacklist. Any further attempts using this IP address will be blocked for the time period specified as the
Block Duration. The default setting for this function is disable. Some attack types are denied
immediately without using the Blacklist function, such as Land attack and Echo/CharGen scan.
Intrusion Detection: If enabled, IDS will block Smurf attack attempts. Default is disable
.
Block Duration:

URL Filter
URL (Uniform Resource Locator – e.g. an address in the form of http://www.abcde.com or
http://www.example.com) filter rules allow you to prevent users on your network from accessing particular
websites by their URL. There are no pre-defined URL filter rules; you can add filter rules to meet your
requirements.
Enable/Disable: To enable or disable the URL Filter feature.
Block Mode: A list of the URL filter rule time modes from which you can choose. The default is set to
Always On.
ꢂ
ꢂ
Disabled: No action will be performed by the Block Mode.
Always On: Action is enabled. URL filter rules will be monitoring and checking at all hours of
the day.
ꢂ
TimeSlot1 ~ TimeSlot16: these are user-defined time periods. You may specify the time
period during which the URL filter rules apply, i.e. during working hours. For setup and details,
refer to Time Schedule section.
Keywords Filtering: Allows blocking by specific keywords within a particular URL rather than having to
specify a complete URL (e.g. to block any image called “advertisement.gif”). When enabled, your
specified keywords list will be checked to see if any keywords are present in URLs accessed to determine
if the connection attempt should be blocked. Please note that the URL filter blocks web browser (HTTP)
connection attempts using port 80 only.
For example, if the URL is http://www.abc.com/abcde.html, it will be dropped if the keyword “abcde”
occurs in the URL.
Domains Filtering: This function checks the whole URL (not the IP address) in URLs accessed against
your list of domains to block or allow. If it is matched, the URL request will be sent (Trusted) or dropped
(Forbidden). For this function to be activated, both check-boxes must be checked. Here is the
checking procedure:
1.
The router checks the domain in the URL to determine if it is in the trusted list. If it is, the
connection attempt is sent to correct the remote web server.
2. If not, the router checks if the domain is listed in the forbidden list. If it is, then
the connection attempt will be dropped.

If the packet does not match either of the above two items, it is sent to the remote web
server.
Please note that the completed URL, “www” + domain name should be specified. For
example to block traffic to www.google.com.au, enter “www.google” or
“www.google.com”
In the example below, the URL request for www.abc.com will be sent to the remote web server because it is
listed in the trusted list, whilst the URL request for www.google or www.google.com will be dropped,
because www.google is in the forbidden list.
Example: Andy wishes to disable all WEB traffic except for ones listed in the trusted domain, which
would prevent Bobby from accessing other web sites. Andy selects both check boxes in Domain
Filtering and thinks that this will stop Bobby.But Bobby knows this function, Domain Filtering, ONLY
disables all WEB traffic except for Trusted Domain, BUT not connections using IP addresses. In this
situation, the Block surfing by IP address function can be handy and helpful to Andy.

Restrict URL Features: This function enhances your URL rules.
ꢂBlock Java Applet: This function can block Web content that includes a Java Applet. This is to
prevent someone who wants to damage your system via standard HTTP protocol.
ꢂBlock surfing by IP address: This prevents someone who uses the IP address as URL from
skipping the Domains Filtering function. This is only Activate if Domain Filtering is enabled.

IM / P2P Blocking
IM, short for Instant Messaging, is required to use client program software that allows users to
communicate, exchanging text message, with other IM users, in real time, over the Internet. A P2P
application, known as Peer-to-Peer, is a group of computer users who share files to specific groups of
people across the Internet. Both Instant Messaging and Peer-to-Peer applications make communication
faster and easier, but your network can become increasingly insecure at the same time. This router’s IM
and P2P blocking system helps users to restrict LAN computers from access to the commonly used IM,
Yahoo and MSN, and P2P, BitTorrent and eDonkey, applications over the Internet.

VPN - Virtual Private Networks
Virtual Private Networks are a way to establish secured communication tunnels to an organization’s
network via the Internet. Your router supports three main types of VPN (Virtual Private Network), PPTP,
IPSec and L2TP.
PPTP (Point-to-Point Tunnelling Protocol)
There are two types of PPTP VPN’s supported; Remote Access and LAN-to-LAN (Please read below
for more information.). Click Create to configure a new VPN connection.
After you have created PPTP connection, it’s account status will be displayed. (See example above).
ꢂ Enable / Disable: This function activates or deactivates the PPTP connection. If you wish to disable
the tunnel, select the Disable radio button and click on the Apply button to deactivate the connection.
Name: The user-defined name of the connection.
Type: This refers to your whether your router operates as a client or a server, select eather Dialout for
client, or Dialin for server.
Status: This informs you of your PPTP tunnel connection condition.

Billion 800VGT Router
PPTP Connection - Remote Access
Connection Name: A user-defined name for the connection (e.g. “connection to office”).
Type: Select Dial Out if you want your router to operate as a client (connecting to a remote VPN server,
e.g. your office server), select Dial In if you want your router to operate as a VPN server.
ꢂWhen configuring your router as a Client, enter the remote Server IP Address (or Domain
Name) you wish to connection to.
ꢂWhen configuring your router as a server, enter the Private IP Address Assigned to Dial in
User address.
Username: If you are a Dial-Out user (client), enter the username provided by your Host. If you are a
Dial-In user (server), enter your own username.
Password: If you are a Dial-Out user (client), enter the password provided by your Host. If you are a
Dial-In user (server), enter your own password.
PPP Authentication Type: Default is Auto. This is the correct setting if you want the router to determine
which authentication type to use, or else you can manually specify CHAP (Challenge Handshake
Authentication Protocol) or PAP (Password Authentication Protocol) if you know which type the server is
using (when acting as a client) When acting as a server, specify the authentication type you want clients
connecting to your router to use. When using PAP, the password is sent unencrypted, whilst CHAP
encrypts the password before sending, and also allows for challenges at different periods to ensure that
an intruder has not replaced the original client.
Data Encryption: Data sent over the VPN connection can be encrypted by an MPPE algorithm. Default
is Auto and this means that this setting is negotiated when establishing a connection. Alternatively, you
can manually Enable or Disable encryption.
Key Length: The data can be encrypted by MPPE algorithm with 40 bits or 128 bits. Default is Auto
which means that it is negotiated when establishing a connection. 128 bit keys provide stronger
encryption than 40 bit keys.
Mode: You may select Stateful or Stateless mode. The key will be changed every 256 packets when you
select Stateful mode. If you select Stateless mode, the key will be changed in each packet.
Idle Time: Auto-disconnect the VPN connection when there is no activity on the connection for a
predetermined period of time. 0 means this connection is always on.
Active as default route: If you select this option while using Dial-out connection, all packets will route
through the VPN tunnel to the Internet; therefore, activating the function may degrade Internet
performance.

Remote Secure Gateway Address (or Domain Name): The IP address or hostname of the remote VPN
device that is to be connected to when establishing a VPN tunnel.
Remote Network: Set the IP address, subnet or address range of the remote network.
Proposal: Select the IPSec security method. There are two methods of checking the authentication
information, AH (authentication header) and ESP (Encapsulating Security Payload). Use ESP for greater
security so that data will be encrypted and authenticated. Using AH data will be authenticated but not
encrypted.
Authentication: Authentication establishes the integrity of the datagram and ensures it is not tampered
with during transmission. There are three options, Message Digest 5 (MD5), Secure Hash Algorithm
(
SHA1) or NONE. SHA1 is more resistant to brute-force attacks than MD5, however it is slower.

Internet). There are three modes, MODP 768-bit, MODP 1024-bit and MODP 1536-bit. MODP stands for
Modular Exponentiation Groups.
Pre-shared Key: This is for the Internet Key Exchange (IKE) protocol, a string from 4 to 128 characters.
Both sides should use the same key. IKE is used to establish a shared security policy and authenticated
keys for services (such as IPSec) that require a key. Before any IPSec traffic can be passed, each router

ꢂPhase 1 (IKE): Used to issue an initial connection request for a new VPN tunnel. Any value
can be selected between 5 and 15,000 minutes. The default is 480 minutes.
ꢂPhase 2 (IPSec): Used to negotiate and establish secure authentication. Any value can be
selected between 5 and 15,000 minutes. The default is 60 minutes.
A short SA time increases security by forcing the two parties to update the keys. However, every
time the VPN tunnel re-negotiates, access through the tunnel will be temporarily disconnected.
Ping to Keep Alive:
PING to the IP: The router is able to IP Ping the remote PC with a specified IP address and alert the user
when the connection fails. Once the alert message is received, the router will drop this tunnel
connection. The connection will need to be re-established. Default setting is 0.0.0.0 which disables this
function.
Interval: This sets the time interval between Pings to the IP function to monitor the connection status.
Default interval setting is 10 seconds. Time interval can be set to any value between 0 and 3600

L2TP Connection - Remote Access
L2TP VPN Connection
Connection Name: A User-defined name for the connection (e.g. “connection to office”).
Type: Select Dial Out if you want your router to operate as a client (connecting to a remote VPN server,
e.g. your office server), select Dial In if you wish your router to operate as a VPN server.
ꢂ When configuring your router as a Client, enter the remote Server IP Address (or Hostname)
that you wish to connection to.
ꢂ When configuring your router as a server, enter the Private IP Address Assigned to Dial in
User (this is the IP address that the remote client will be assigned when it connects) .
Username: If you are a Dial-Out user (client), enter the username provided by your Host (Your username
for the server that you are connecting to) . If you are a Dial-In user (server), enter the username that the
connecting client will use to connect to your router.
Password: If you are a Dial-Out user (client), enter the password provided by your Host Your password
for the server that you are connecting to). If you are a Dial-In user (server), enter the password that the
connecting client will use to connect to your router
PPP Authentication Type: Default is Auto. This will allow the router to determine the best suited
authentication type. Alternatively, you can manually specify CHAP (Challenge Handshake Authentication
Protocol) or PAP (Password Authentication Protocol) if you know which type the server is using (when
acting as a client) If your router is acting as a server, specify the authentication type you want clients
connecting to you to use. When using PAP, the password is sent unencrypted, whilst CHAP encrypts the
password before sending, and also allows for challenges at different periods to ensure that the client has
not been replaced by an intruder.
Idle Time: When there is no activity on the connection for this pre-determined Idle time, the VPN
connection is Auto-disconnected. 0 means this connection is always on.

Active as default route: Normally used when the mode is set to Dial-out. If this is selected, all packets,
including internet packets, will route through the VPN tunnel; If this function is enabled, the performance
of your Internet connection may be degraded Click Apply after changing the settings.
L2TP over IPSec (L2TP/IPSec) VPN Connection
IPSec: Enable to enhance your L2TP VPN security.
Authentication: Authentication establishes the integrity of the datagram and ensures it is not tampered
with during transmission. There are three options, Message Digest 5 (MD5), Secure Hash Algorithm
(
SHA1) or NONE. SHA1 is more resistant to brute-force attacks than MD5, however it is slower.
ꢂ
MD5: A one-way hashing algorithm that produces a 128−bit hash.
SHA1: A one-way hashing algorithm that produces a 160−bit hash.
ꢂ
Encryption: Select the encryption method from the pull-down menu. There are four options, DES, 3DES,
AES and NONE. NONE means that the connection is a tunnel only, with no encryption. 3DES and AES
are more powerful but increase latency.
ꢂ
ꢂ
ꢂ
DES: Stands for Data Encryption Standard, it uses a 56 bit encryption method.
3DES: Stands for Triple Data Encryption Standard, it uses a 168 (56*3) bit encryption method.
AES: Stands for Advanced Encryption Standards, it uses a 128 bit encryption method.
Perfect Forward Secrecy: Choose whether to enable PFS, using Diffie-Hellman public-key cryptography
to change encryption keys during the second phase of VPN negotiation. This function provides better
security, but extends the VPN negotiation time. Diffie-Hellman is a public-key cryptography protocol that
allows two parties to establish a shared secret over an unsecured communication channel (i.e. over the
Internet). There are three modes, MODP 768-bit, MODP 1024-bit and MODP 1536-bit. MODP stands for
Modular Exponentiation Groups.
Pre-shared Key: This key is for Internet Key Exchange (IKE) protocol and is a string of between 4 and
128 characters. Both sides should use the same key. IKE is used to establish a shared security policy and it
authenticates keys for services (such as IPSec) that require a key. Before any IPSec traffic can be
passed, each router must be able to verify the identity of its peer. This can be done by manually entering
the pre-shared key into both sides of the connection (router or hosts).
Remote Host Name (Optional): Enter hostname of the remote VPN device. This is a tunnel identifier
and should match the Remote VPN device hostname. If it matches the tunnel will be connected;
otherwise, it will be dropped.
Caution: This is only when the router acts as a VPN server. This option should be used by advanced
users only.
Local Host Name (Optional): Enter the hostname of the Local VPN device that establishes the VPN
tunnel. By default, the Router’s default Hostname is home.gateway.
Tunnel Authentication: This enables the router to authenticate both the L2TP remote client and L2TP
host. This is only valid when the L2TP remote client supports this feature.
Secret: The secure password length should be 16 characters (This may include numbers and/or
characters.)

VoIP - Voice over Internet Protocol
The VoIP functionality enables telephone calls to be placed through your existing Internet connection
instead of going through the PSTN (Public Switched Telephone Network). It is not only cost-effective,
especially for long distance telephone calls, but also allows toll-quality voice calls to be placed over the
Internet.
After completing your VoIP configuration, remember to apply the changes,
SAVE CONFIG and restart to activate your VoIP functionality.
Attention
Here are the items within the VoIP section: Wizard, General Settings, Phone Port, PSTN Dial Plan,
VoIP Dial Plan and Ring &Tone.
Wizard
This section provides an easy setup process for your VoIP service. Phone port 1 and 2 can be registered
to different SIP Service Providers.
VoiceQoS
DSCP Marking: Differentiated Services Code Point (DSCP), it is the first 6 bits in the ToS byte. DSCP
Marking allows users to assign specific application traffic to be executed in priority by the next Router on
the backbone network, based on the DSCP value.
Note: To make use of this functionality ensure that all of the routers in the backbones network have the capability of

The PSTN Environment Adjustment options will help you to adjust the on hook and off hook voltage
detection values for your environment. The actual levels are determined by your environment including
the number and type of telephones used. The default values provided are suitable for the South African
PSTN network, and there should not be modified. If, however, you are connecting the line port to a PABX,
and you experience problems with placing calls, then you may wish to modify these parameters.
Note: ON HOOK means hung up.
To take your phone OFF HOOK, lift the receiver then press Hook/Flash until you hear your normal PSTN
dial tone, not your VoIP dial tone. Wait several seconds and then press Check Level.
You should check the OFF HOOK value for each telephone you have connected to this device. Set the
OFFHOOK voltage to the lowest setting registered for all your telephones, e.g. if your telephones return
values of 4, 5 and 7 then you should set your OFFHOOK voltage to 4.
Note: The detected values will not automatically be set by the Check Level function; you must enter the lowest level
detected after testing all your telephones.

Codec Preference
A codec is a Coder-Decoder and is used for data signal conversion. The priority position sets the priority
of each codec; Priority 1 is the top priority.
G.729: This type of codec encodes and decodes the voice information into a single packet which reduces
the bandwidth consumption. 8kbps of bandwidth is needed.
G.711µ-LAW: This codec uses a basic non-compressed encoder and decoder technique. µ-LAW uses a
pulse code modulation (PCM) encoder and decoder to convert voice into a 14-bit linear sample. 64kbps
of bandwidth is needed.
G.711A-LAW: This codec uses a basic non-compressed encoding and decoding technique. µ-LAW
uses a pulse code modulation (PCM) encoder and decoder to convert voice into a 13-bit linear sample.
64kbps of bandwidth is needed.
Non-used: This option is only available for Priority 2 and 3. It should be selected if no codec is to be
used in these priority settings.
Note: In the example screen shown above, the codec priority is assigned in the order as G.729 > G.711µ-LAW >

PSTN Dial Plan
This section enables you to configure “VoIP with PSTN switching” on your system. You can define a
range of dial plans to select which calls are routed over VoIP and which are routed over the PSTN line.
Prefix numbers are the essential key to distinguish between VoIP and Regular (PSTN) phone calls. If the
actual numbers dialed matches the prefix number defined in this dial plan, the dialed number will be
routed to the PSTN to make a regular call. Otherwise, the number will be routed over the VoIP network.
Reminder! In order to utilize this feature, you must have registered and connected to your SIP Server
first.
Prefix: Specify number(s) for switching to a PSTN call.
Number of Digits: Specify the total number of digits that you wish to dial out. Maximum digit number is
15.
Action: Specify a dialling method that you wish to use when making PSTN call(s).
ꢂDial with Prefix: The complete number that you have dialled will be dialled on the PSTN
(including prefix)
Note: The actual number of valid digits dialled must match the number in the Number of Digits field.
ꢂDial without Prefix: The number that you have dialled will be dialled on the PSTN after the prefix
has been removed from it (excluding prefix).
Note: The actual number of valid digits dialled must match the number in the Number of Digits field
ꢂDial at Timeout: The complete number that you have dialled will be dialled on the PSTN
(including prefix) once a certain time has elapsed since the last digit was dialled.
Note: The actual number of valid digits dialled must NOT EXCEED the number in the Number of Digits field.
ꢂDial at Timeout no prefix: The number that you have dialled will be dialled on the PSTN
after the prefix has been removed, (excluding the prefix) once a certain time has elapsed since
the last digit was dialled.
Note: The actual number of valid digits dialled must NOT EXCEDE the number in the Number of Digits
field
Phone port 1 and 2 will automatically default to the PSTN line when:
- The router is Powered Down
- Internet Service Fails, i.e., lost of WAN IP Address/connection
- The SIP option is disabled. See the VoIP General Setting section.
- Calls that are placed match the rule(s) defined in the PSTN Dial Plan.
- The SIP service is not accessible. This does not include when :

the actual phone number dialled using localcheap.com as a provider.
2) Phone 1: For International calls: I use longdischeap.com who charge $0.05 per minute for all
International long distance calls. I set a dial rule, 0[2456]x.T<@Long_dist_Cheap>, on my phone
port 1.
Longislcheap.com is one of the VoIP providers I set in the User-defined profile. No prefix is attached to
the dialled number when I dial any number beginning with 0 , followed by 2, 4, 5 or 6 and then the rest of
the phone number. If 02016148513295 is dialled, 0-2-016148513295 is the actual phone number
dialled using longdischeap.com as a provider.
3) Phone 2: For Mobile calls, I use mobilecheap.com who charge $0.25 per minute for all local mobile
calls. I set a dial rule, <123:09>39x.T, on my phone port 2.

Turn the Do Not Disturb mode on
This mode enables a “Do Not Disturb” feature on a phone, such
that any phone which calls it will receive an engaged tone and the
called phone will not ring. For example, B enters *20 and hangs
up. A makes a call to B, but receives the engaged tone. Phone B
does not ring.
*20
*80
Set the Do Not Disturb mode off
Set the number for Speed dial code ‘x’, where ‘x’ is a number
between 2 and 9.
Note: <x> is a number between 2 and 9, and <number> is the
number to dial. To dial a speed dial number from a phone
connected to the VoIP Router , dial :
*74<x><number>#
<x>#, where <x> is a number between 2 and 9.
These settings will affect your setting on the Speed Dial page of
the WEB GUI.
This is how to make a Blind Call Transfer. With this function, the
specified <phone-number> is the number that you wish to transfer
the call to. This function is for a SIP service only.
Note: You use Blind Call Transfer when you have a call in
progress (incoming or outgoing) and decide you wish to transfer
the call to another phone. To transfer the call, perform the following
steps:
*90<phone-number>
1. Hook-flash to get a dial tone.
2. Dial *90<phone-number> (e.g. *907401). After hearing the
confirmation tone, you can hang up. The transferred call will hear a
ringback tone, and the third-party phone (the one that the call has
been forwarded to)_will be rung. When the third-party phone is
picked up, the transferred call will be connected.
If the third-party phone does not answer, the caller being
transferred must hang up to cancel the connect attempt.

Mission-critical applications
Often, a VPN connection is a mission-critical application for exchanging data between Head and Branch
offices.
This mission-critical application must be connected smoothly, without any dropping. To ensure this, you
should set the priority to the high level to preventing any other applications from saturating the bandwidth.
Voice applications
Voice applications are latency-sensitive. Most VoIP devices use the SIP protocol, which automatically
assigns a port number. . This means that it is better to use a fixed IP address to catch VoIP packets and
rout them as high priority traffic.
The settings shown above will help to improve the quality of your VoIP service when the link is fully
loaded.
Restricted Application
Some users will setup a FTP server for downloading of their files by means of FTP.
The above settings will help to limit utilization of upstream bandwidth by the FTP connections. A time
schedule can be implemented to limit file downloads to non-busy times.
Advanced setting by using IP throttling
With IP throttling you can specify more detail for bandwidth allocation; even if applications are located on
the same level.
Upstream: 928kbps (29*32kbps)
Mission-critical Application: 192kbps (6*32kbps)
Voice Application: 128kbps (4*32kbps)
Restricted Application: 160kbps (5*32kbps)
Other Applications: 448kbps (14*32kbps)

Sometime your customers or friends may upload their files to your FTP server and that will saturate your
downstream bandwidth. The settings below will help you to limit bandwidth for such a application that
needs restriction.
Virtual Server (known as Port Forwarding)
In TCP/IP and UDP networks, a port is a 16-bit number used to identify which application program
incoming connections should be delivered to. Some ports have numbers that are pre-assigned to them by
the IANA (the Internet Assigned Numbers Authority), and these are referred to as “well-known ports”.
Servers follow the well-known port assignments so clients can locate them.
If you wish to run a server, or any application (e.g. Peer-to-peer/P2P software such as instant messaging
applications and P2P file-sharing applications) on your network that can be accessed from the WAN (i.e.
from machines on the Internet that are outside your local network, and you are using NAT (Network
Address Translation), then you will need to configure your router to forward these incoming connection
attempts using specific ports to the computer on your network that is running the application/server. You
will also need to use port forwarding if you want to host an online game server.
The reason for this is that when using NAT, your publicly accessible IP address will be used by and point
to your router, which then needs to deliver all traffic to the private IP addresses used by your PCs. Please
see the WAN configuration section of this manual for more information on NAT.
The device can be configured as a virtual server so that remote users accessing services such as Web or
FTP services on the routers public (WAN) IP address can be automatically redirected to local servers on
the LAN network. Depending on the requested service (TCP/UDP port number), the router redirects the
external service request to the appropriate server within the LAN network

Add Virtual Server
Because NAT can act as a “natural” Internet firewall, your router protects your network from being
accessed by outside users when NAT is enabled - all incoming connection attempts will point to your
router unless you specifically created Virtual Server entries to forward those ports to a computer on your
network.
When your router needs to allow outside users to access internal servers, e.g. a web server, FTP server,
Email server or game server, the router can act as a “virtual server”. You can set up a local server with a
specific port number for the service to use, e.g. web/HTTP (port 80), FTP (port 21), Telnet (port 23),
SMTP (port 25), or POP3 (port 110), When an incoming access request for a specified port is received by
the router, it will be forwarded to the corresponding internal server.
Time Schedule: The user-defined time period to enable your virtual server. You may specify a time
schedule or Always on for the use of this Virtual Server Entry. For setup and detail, refer to Time
Schedule section
Application: A user-defined description used to identify this entry. You can click

20 predefined rules are available. Click the Radio button to select the rule; Application,
Protocol and External/Redirect Ports will be automatically filled in after the selection.
Protocol: This is the protocol supported by the virtual server. In addition to specifying the port number to
be used, you will also need to specify the protocol used. The protocol used is determined by the particular
application. Most applications will use TCP or UDP.
External Port: The Port number on the Remote/WAN side used when accessing the virtual server.
Redirect Port: The Port number used by the Local server in the LAN network.
Internal IP Address: The private IP in the LAN network, which will be providing the virtual server
application. List all existing computers currently connected to the network. You may assign a
computer with an IP address or a MAC address from this list.

Example:
If you would like to remotely access your routers’ Web/HTTP interface all the time, you would need to
enable port number 80 (Web/HTTP) and map it to the Router’s LAN IP Address. All incoming HTTP
requests on the WAN network will then be forwarded to the router’s IP address of 192.168.1.254. Since
port number 80 is already a predefined rule, click Helper in the Application section
rules window will pop and you can select HTTP_Sever.

Redirect Port: 80-80
IP Address: 192.168.1.254
Edit: Click on this to edit this virtual server application.
Delete: Click on this to delete this virtual server application.
Using port forwarding has security implications, since outside users will be able
to connect to Computers on your network. For this reason you are advised to
add specific Virtual Server entries only for the ports that your application
actually requires, instead of using the DMZ function. Using the DMZ function
will result in all connection attempts from the WAN network having access to
the public IP specified in the DMZ config section.
If you have disabled the NAT option in the WAN-ISP section, the Virtual Server
function will not work.
If the DHCP server option is enabled, you have to be very careful when
assigning the IP addresses of virtual servers so that you avoid conflicting IP
addresses. The easiest method of configuring Virtual Servers is to manually
assign static IP address to each virtual server Computer, with an address that
does not fall into the range of IP addresses that are to be issued by the DHCP
server. These manually configured IP addresses MUST still be in the same
subnet as the router.

Edit DMZ Host
A DMZ Host is a computer on the LAN that is completely exposed to the Internet. When you have
configured a particular internal IP address as the DMZ Host, all incoming packets will be checked by the
routers firewall and NAT algorithms, and if the packet does not use a port number that has been assigned
by any Virtual Server entry, it will be passed to the DMZ host
Cautious: This local computer, which is exposed to the Internet, may face a variety of security risks.you should
make quite sure that it is adequately protected.

Time Schedule
The Time Schedule function supports up to 16 time slots, helping you to manage your Internet connection.
In each time profile, you may schedule specific day(s) i.e. Monday through Sunday to restrict or allowing
the usage of the Internet by users or applications.
This Time Schedule correlates closely to real time. Since router does not have a real time clock on board;
it uses the Simple Network Time Protocol (SNTP) to get the current time from an SNTP server from the
Internet. Refer to Time Zone for details. Your router time should correspond with your local time. If the
time settings on you router are not set correctly, the Time Schedule will not function properly.

Dynamic DNS
The Dynamic DNS function allows you to alias a dynamic IP address to a static hostname, allowing users
whose ISP does not assign them a static IP address to use a domain name. This is especially useful for
hosting servers via your ADSL connection, so that anyone wishing to connect to you may use your
domain name, rather than having to use your dynamic IP address, which changes from time to time. This
dynamic IP address is the WAN IP address of the router, which is assigned to you by your ISP.
You will first need to register and establish an account with the Dynamic DNS provider using their website,
for example http://www.dyndns.org/
There are more than 5 DDNS services supported.
ꢂ
Disable: Select this option to disable the Dynamic DNS function.
ꢂEnable: Select this option to enable the Dynamic DNS function. The following fields will be
activated and must be filled in:
Dynamic DNS Server: Select the DDNS service you have established an account with.
Domain Name, Username and Password: Enter your registered domain name and your username and
password provided by your DDNS service.
Period: Set the time period between updates. This is the interval after which your router will exchange
information with the DDNS server. In addition to updating periodically as per your settings, the router will
perform an update when your dynamic IP address changes.

Device Management
The Device Management configuration settings allow you to control your router’s security options and
device monitoring features.
Embedded Web Server ( 2 Management IP Accounts)
HTTP Port: This is the port number of the router’s embedded web server (for web-based configuration.)
The default value is the standard HTTP port, 80. Users may specify an alternative if, for example, they are
running a web server on a PC within their LAN.
Management IP Address: You may specify the IP addresses allowed to logon and access the router’s
web server. Setting the IP address to 0.0.0.0 will disable IP address restrictions, allowing users to login
from any IP address.
Expire to auto-logout: Specify a time frame for the system to auto-logout the user’s configuration
session.
For Example: User A changes the routers HTTP port number to 100, specifies their own IP address
of10.0.0.55, and sets the logout time to be 100 seconds. The router will only allow User A access
from the IP address 10.0.0.55 to logon to the Web GUI by typing: http://10.0.0.2:100 in their web browser.
100 seconds, the device will automatically logout User A.

Universal Plug and Play (UPnP)
UPnP offers peer-to-peer network connectivity for PCs and other network devices, along with control and
data transfer between devices. UPnP offers many advantages for users running NAT routers through
UPnP NAT Traversal. On supported systems, it makes tasks such as port forwarding much easier by
letting the application control the required settings, thus removing the need for the user to control the
advanced configuration of their router.
Both the user’s Operating System and the relevant application must support UPnP in addition to the
router. Windows XP and Windows Me natively support UPnP (when the component is installed), and
Windows 98 users may install the Internet Connection Sharing client from Windows XP in order to
support UPnP. Windows 2000 does not support UPnP.
ꢂ
Disable: Select this option to disable the router’s UPnP functionality.
Enable: Select this option to enable the router’s UPnP functionality.
ꢂ
UPnP Port: The default port setting is 2800. It is highly recommended that users use this port value. If
this value conflicts with other ports that are already being used, you may wish to change it.
SNMP Access Control (Software on a PC within the LAN is required in order to utilize this function) –
Simple Network Management Protocol.
SNMP V1 and V2:
Read Community: Specify a name to be identified as the Read Community, and an IP address. This
community string will be checked against the string entered in the configuration file. Once the string name is
matched, the user on this IP address will be able to view the data.
Write Community: Specify a name to be identified as the Write Community, and an IP address. This
community string will be checked against the string entered in the configuration file. Once the string name is
matched, users on this IP address will be able to view and modify the data.
Trap Community: Specify a name to be identified as the Trap Community, and an IP address. This
community string will be checked against the string entered in the configuration file. Once the string name is
matched, users on this IP address will be sent SNMP Traps.
SNMP V3:
Specify a name and password for authentication. And define the access rights from identified IP address.
Once the authentication has succeeded, users from this IP address will be able to view and modify the
data.
SNMP Version: SNMPv2c and SNMPv3
SNMPv2c is a combination of the enhanced protocol features of SNMPv2 without the SNMPv2 security.
The "c" comes from the fact that SNMPv2c uses the SNMPv1 community string paradigm for "security",
but is widely accepted as the SNMPv2 standard.
SNMPv3 is a strong authentication mechanism, providing authorization with fine granularity for remote
monitoring.
Traps supported: Cold Start, Authentication Failure.
