Before You Use  
Before You Use  
Thank you for choosing the Asymmetric Digital Subscriber Line (ADSL) Router. With the  
asymmetric technology, this device runs over standard copper phone lines. In addition, ADSL allows  
you to have both voice and data services in use simultaneously all over one phone line.  
ADSL Router is designed to offer cost-effective high-speed services for home or office users. It  
provides a downstream rate of up to 8 Mbps and upstream rate of up to 1 Mbps for ADSL connection,  
even offers auto-negotiation capability for different flavors (G.dmt, G.lite, T1.413 Issue 2 and so on)  
according to central office DSLAM’s settings (Digital Subscriber Line Access Multiplexer). Also the  
feature-rich routing functions are seamlessly integrated to ADSL service for existing corporate or  
home users. Now users can enjoy various bandwidth-consuming applications via ADSL Router.

Subscription for ADSL Service  
To use the ADSL Router, you have to subscribe for ADSL service from your broadband service  
provider. According to the service type you subscribe, you will get various IP addresses:  
Dynamic IP: If you apply for dial-up connection, you will be given an Internet account with  
username and password. You will get a dynamic IP by dialing up to your ISP.  
Static IP address: If you apply for full-time connectivity, you may get either one static IP address or  
a range of IP addresses from your ISP. The number of IP addresses varies according to different  
ADSL service provider.

Configuring Other Routers on Your LAN  
It is essential that all IP packets for devices that are not on the local LAN can be passed to the Router,  
so that they can be forwarded to the external LAN, WAN, or Internet. To achieve this, the local LAN  
must be configured to use the Router as the default route or default gateway.  
Local Router  
The local router is the Router installed on the same LAN segment as the Router. This router requires  
that the default route is the Router itself. Typically, routers have a special entry for the default route. It  
should be configured as follows.  
Destination:  
Subnet Mask:  
Gateway:

Other routers on the local LAN must use the Router’s Local Router as the Default Route. The entries  
will be the same as the Router’s local router, with the exception of the Gateway IP Address.  
ꢀ
For a router with a direct connection to the Router’s local Router, the Gateway IP Address is the  
address of the Router’s local router.

Secondary DNS server:  
Type in the secondary DNS server.  
If you are satisfied the settings, click Apply.  
NAT - Virtual Servers  
The Router implements NAT to let your entire local network appear as a single machine to the  
Internet. The typical situation is that you have local servers for different services and you want to  
make them publicly accessible. With NAT applied, it will translate the internal IP addresses of these  
servers to a single IP address that is unique on the Internet. NAT function not only eliminates the need  
for multiple public IP addresses but also provides a measure of security for your LAN.  
When the router receives an incoming IP packet requesting for access to your local server, the router  
will recognize the service type according to the port number in this packet (e.g., port 80 indicates  
HTTP service and port 21 indicates FTP service). By specifying the port number, you tell the router  
which service should be forwarded to the local IP address you specify.  
After you setting the virtual server you should modify the filter rule whichever port and service you  
set on virtual server. Because the firewall has protect the route by filter rule so that you should update  
the filter rule after you set up virtual server.  
Virtual Server allows you to make servers on your LAN accessible to Internet users. Normally,  
Internet users would not be able to access a server on your LAN because:  
ꢀ
ꢀ
Your server does not have a valid external IP Address.  
Attempts to connect to devices on your LAN are blocked by the firewall in this device.  
The Virtual Server feature solves these problems and allows Internet users to connect to your servers,

IP Address seen by Internet Users  
Please note that, in the above picture, both Internet users are connecting to the same IP address, but  
using different protocols.  
To Internet users, all virtual servers on your LAN have the same IP Address. This IP Address is  
allocated by your ISP. This address should be static, rather than dynamic, to make it easier for Internet  
users to connect to your Servers. However, you can use Dynamic DNS feature to allow users to  
connect to your virtual servers by using a URL, instead of an IP address.  
To set a virtual server, please open the  
Virtual Servers item from the Advanced  
Setup - NAT menu.  
Add New Virtual Servers  
To add a new Virtual Server, please click Add. In the “Select from the following list” drop-down list,  
you can select required entry  
Select from the following list:  
Choose one of the services from the list,  
such as SMTP, WEB, FTP, DNS and so on.  
The corresponding data will be shown on the  
data boxes below.  
Customized service:  
Type a new service name for building a  
customized service for specific reason.  
Protocol:  
Select a protocol for the service that you  
choose.  
External port for this service:

automatically when you select a service for  
using. You can type a new number if you  
want to do a customized service.  
Internal port for this service:  
The port number will be shown  
automatically when you select a service for  
using. You can type a new number if you  
want to do a customized service.  
Internal server IP address:  
Type in the server IP address when you want  
to specify a certain address for the virtual  
server.  
1. Select the protocol type from the drop-  
down list.  
2. Enter the TCP/IP port information in the  
External and Internal Port for this service  
fields.  
3. Enter the IP address of the internal server  
in the Internal server IP Address filed.  
4. Click Apply.  
IP addresses can be automatically redirected to local servers configured with private IP addresses. In  
other words, depending on the requested service (TCP/UDP port number), the router redirects the  
external service request to the appropriate server (located at another internal IP address).  
After adding a new virtual server, click  
Apply to view the new virtual server. The  
following screen will be shown to display  
the status for this new one.  
If you do not want the new server that you  
added, please check the one and click  
Remove to discard it. Or if you want to add  
another one again, click Add to add a new  
one. And if you are satisfied with all settings  
that you configure here, click Save.  
Connecting to the Virtual Servers  
Once configured, anyone on the Internet can connect to your Virtual Servers. They must use the  
Internet IP Address (the IP Address allocated to you by your ISP.) For example,  
Http://203.70.212.52  
Ftp://203.70.212.52  
It is more convenient if you are using a Fixed IP Address from your ISP, rather than Dynamic.  
However, you can use the Dynamic DNS feature to allow users to connect to your Virtual Server  
through a URL, rather than an IP Address.  
NAT - DMZ Host  
Direct Mapping Zone (DMZ) uses a technology that makes Router forwarding all incoming packet to  
internal specific server.

Firewall  
The firewall is a software that interrupts the data between the Internet and your computer. It is the  
TCP/IP equivalent of a security gate at the entrance to your company. All data must pass through it,  
and the firewall (functions as a security guard) will allow only authorized data to be passed into the  
LAN.  
What the firewall can do? It can:  
ꢀ
ꢀ
deny or permit any packet from passing through explicitly  
distinguish between various interfaces and match on the following fields:  
ꢋ
source and destination IP address

Chapter 4: Web Configuration  
ꢋ
port  
To keep track of the performance of IP Filter, a logging device is used which supports logging of the  
TCP/UDP and IP packet headers and the first 129 bytes of the packet (including headers) when a  
packet is successfully passed through, a packet is blocked from passing through and it matches a rule  
setup to look for suspicious packets  
Filtering by IP address  
An IP Filter can:  
ꢀ
ꢀ
act as a Network Address Translator (NAT)  
pass the data from the Virtual server to Internet  
An example for firewall setup:  
This picture is the most common and easiest way to employ the firewall. Basically, you can install a  
packet-filtering router at the Internet gateway and then configures the filter rule in the router to block  
or filter protocols and addresses. The systems behind the router usually have a direct access to the  
Internet, however some dangerous services such as NIS and NFS are usually blocked.  
For the security of your router, set the firewall is an important issue.  
Diagnostics  
To check the link status for the network and your computer, a diagnostic test can guide you to detect  
the network problem. The testing items are listed and accomplished one by one. If the previous one is  
failed, than the items below that failed one will be failed too. Use this diagnostic test to detect the  
connectivity mistakes whenever you happen to the linked problem.

SNMP Setting  
The SNMP, the abbreviation of Simple Network Management Protocol, is used to refer to a collection  
of specifications for network management that include the protocol itself, the definition of data  
structures and associated concepts.  
A management station performs the monitoring function by retrieving the value of MIB objects. The  
51  
Download from Www.Somanuals.com. All Manuals Search And Download.  
ADSL Router User Manual  
management station and agents are linked by a network management protocol that is SNMP. The  
SNMP includes three key capabilities, get, set and trap. A single management station can handle many  
agents as long as SNMP remains relatively “simple”, so the number can be high (hundreds or so).  
The following picture is the typical configuration of protocols for SNMP. As for a stand-alone  
management station, a manager process controls access to a central MIB at the management station  
and provides an interface to the network manager. The manager process achieves network  
management by using SNMP, which will be implemented on top of the UDP, IP and the relevant  
network-dependent protocols (e.g., Ethernet).  
For an agent device that supports other applications, such as FTP, both TCP and UDP are required. An  
agent may issue a trap message in response to an event that effects the MIB and the underlying  
managed resources.  
Note: There are no ongoing connections are maintained between a management station and its agents.  
Instead, each exchange is a separate transaction between a management station and an agent.  
Each agent is responsible for notifying the management station of any unusual event; for example, if  
the agent crashes and is rebooted, a link fails or an overload condition as defined by the packet load  
crosses some threshold. These events are communicated in SNMP messages known as traps.  
Please select the SNMP menu from Management. The dialog will appear.

Description:  
In this deployment environment, we make up a private IP network of 192.168.1.1. NAT function is  
enabled to support multiple clients to access Internet.  
In this example, the ADSL Router acts as a NAT device which translates a private IP address into a  
public address. Therefore multiple users can share with one public IP address to access Internet  
through this router. The public address can be a static public address that is pre-assigned by ISP or a  
dynamic public address that is assigned by ISP DHCP server.  
Configuration:  
1.  
Start up your browser and type 192.168.1.1 as the address to enter this ADSL web-based  
manager.

Troubleshooting  
If the suggested solutions in this section do not resolve your issue, contact your system administrator  
or Internet service provider.  
Problems with LAN  
PCs on the LAN can not get IP addresses from the ADSL Router.  
The chances are that the interface used as DHCP server is modified and the client PCs do not renew IP  
addresses.  
If your DHCP server is enabled on Private IP Address previously and you modify the interface to  
Public IP Address, the client PCs should renew IP addresses.  
The PC on the LAN cannot access the Web page of the ADSL Router.  
Check that your PC is on the same subnet with the ADSL Router.  
The virtual server can’t be access after setting virtual server.  
Check the filter rule of the port that virtual server service setting for example, the virtual server  
service set FTP 21 you need update the filter rule of the ftp 21 Direction setting: Choose filter the  
packets that incoming action (In Bound) are Allow on the interface.  
Problems with WAN  
You cannot access the Internet.  
ꢀ
Check the physical connection between the ADSL Router and the LAN.  
If the LAN LED on the front panel is off or keeps blinking, there may be problem on the cable  
connecting to the ADSL Router.  
At the DOS prompt, ping the IP address of the ADSL Router, e.g, ping 192.168.1.1. If the  
following response occurs:  
Relay from 192.168.1.1 bytes=32 time=100ms TTL=253  
Then the connection between the ADSL Router and the network is OK.  
If you get a failed ping with the response of:  
Request time out  
Then the connection is fail. Check the cable between the ADSL Router and the network.  
ꢀ
Check the DNS setting of the ADSL Router.  
At the DOS prompt, ping the IP address of the DNS provided by your ISP. For example, if your  
DNS IP is 168.95.1.1, then ping 168.95.1.1. If the following response occurs:

Chapter 6: Troubleshooting  
Relay from 168.95.1.1 bytes=32 time=100ms TTL=253  
Then the connection to the DNS is OK.  
If you get a failed ping with the response of:  
Request time out  
Then the DNS is not reachable. Check your DNS setting on the ADSL Router.

Glossary  
ARP (Address Resolution Protocol )  
ARP is a TCP/IP protocol for mapping an IP address to a physical machine address that is  
recognized in the local network, such as an Ethernet address.  
A host wishing to obtain a physical address broadcasts an ARP request onto the TCP/IP  
network. The host on the network that has the IP address in the request then replies with its  
physical hardware address.  
Inverse ARP (In-ARP), on the other hand, is used by a host to discover its IP address. In this  
case, the host broadcasts its physical address and a RARP server replies with the host's IP  
address.  
DHCP (Dynamic Host Configuration Protocol)  
When operates as a DHCP server, the ADSL Router assign IP addresses to the client PCs on  
the LAN. The client PCs “leases” these Private IP addresses for a user-defined amount of  
time. After the lease time expires, the private IP address is made available for assigning to  
other network devices.  
The DHCP IP address can be a single, fixed public IP address, an ISP assigned public IP  
address, or a private IP address.  
If you enable DHCP server on a private IP address, a public IP address will have to be  
assigned to the NAT IP address, and NAT has to be enabled so that the DHCP IP address can  
be translated into a public IP address. By this, the client PCs are able to access the Internet.  
LAN (Local Area Network) & WAN (Wide Area Network)  
A LAN is a computer network limited to the immediate area, usually the same building or  
floor of a building. A WAN, on the other hand, is an outside connection to another network or  
the Internet.  
The Ethernet side of the ADSL Router is called the LAN port. It is a twisted-pair Ethernet  
10Base-T interface. A hub can be connected to the LAN port. More than one computers, such  
as server or printer, can be connected through this hub to the ADSL Router and composes a  
LAN.  
The DSL port of the ADSL Router composes the WAN interface, which supports PPP or RFC  
1483 connecting to another remote DSL device.  
NAT (Network Address Translation) IP Address  
NAT is an Internet standard that translates a private IP within one network to a public IP  
address, either a static or dynamic one. NAT provides a type of firewall by hiding internal IP  
addresses. It also enables a company to use more internal IP addresses.

Chapter 7: Glossary  
If the IP addresses given by your ISP are not enough for each PC on the LAN and the ADSL  
Router, you need to use NAT. With NAT, you make up a private IP network for the LAN and  
assign an IP address from that network to each PC. One of some public addresses is  
configured and mapped to a private workstation address when accesses are made through  
the gateway to a public network.  
For example, the ADSL Router is assigned with the public IP address of 168.111.2.1. With  
NAT enabled, it creates a Virtual LAN. Each PC on the Virtual LAN is assigned with a private  
IP address with default value of 192.168.1.2 to 192.168.2.254. These PCs are not accessible  
by the outside word but they can communicate with the outside world through the public IP  
168.111.2.1.  
Private IP Address  
Private IP addresses are also LAN IP addresses, but are considered “illegal” IP addresses to  
the Internet. They are private to an enterprise while still permitting full network layer  
connectivity between all hosts inside an enterprise as well as all public hosts of different  
enterprises.  
The ADSL Router uses private IP addresses by assigning them to the LAN that cannot be  
directly accessed by the Internet or remote server. To access the Internet, private network  
should have an agent to translate the private IP address to public IP address.  
Public IP Address  
Public IP addresses are LAN IP addresses that can be considered “legal” for the Internet,  
because they can be recognized and accessed by any device on the other side of the DSL  
connection. In most cases they are allocated by your ISP.  
If you are given a range of fixed IP addresses, then one can be assigned to the router and  
the others to network devices on the LAN, such as computer workstations, ftp servers, and  
web servers.  
PVC (Permanent Virtual Circuit)  
A PVC is a logical point-to-point circuit between customer sites. PVCs are low-delay circuits  
because routing decisions do not need to be made along the way. Permanent means that the  
circuit is preprogrammed by the carrier as a path through the network. It does not need to  
be set up or torn down for each session.  
RIP (Routing Information Protocol)  
RIP is a routing protocol that uses the distance-vector routing algorithms to calculate least-  
hops routes to a destination. It is used on the Internet and is common in the NetWare  
environment. It exchanges routing information with other routers. It includes V1, V2 and  
V1&V2, which controls the sending and receiving of RIP packets over Ethernet.  
UDP (User Datagram Protocol)  
UDP is a connectionless transport service that dispenses with the reliability services provided  
by TCP. UDP gives applications a direct interface with IP and the ability to address a  
particular application process running on a host via a port number without setting up a  
connection session.  
Virtual Server  
You can designate virtual servers, e.g., a FTP, web, telnet or mail server, on your local  
network and make them accessible to the outside world. A virtual server means that it is not  
a dedicated server -- that is, the entire computer is not dedicated to running on the public  
network but in the private network.  
VPI (Virtual Path Identifier) & VCI (Virtual Channel Identifier)  
A VPI is a 8-bit field while VCI is a 16-bit field in the ATM cell header. A VPI identifies a link  
formed by a virtual path and a VCIidentifies a channel within a virtual path. In this way, the  
75

cells belonging to the same connection can be distinguished. A unique and separate VPI/VCI  
identifier is assigned in advance to indicate which type of cell is following, unassigned cells,  
physical layer OAM cells, metasignaling channel or a generic broadcast signaling channel.  
Your ISP should supply you with the values.
