4. Setting Up Your ADSL Router This section will guide you through the ADSL router’s configuration. The ADSL router is shipped with a standard PPP configuration. 4.1 Log into Your ADSL Router To configure the ADSL router, launch your web browser. You may get an error message at this point; this is normal. Do not panic! Type the default IP address (192.168.1.1) press the Enter key and the following page, shown in Figure 1 will appear.
The Quick Start page is meant for basic users who only require easy and seamless connectivity to the Internet, without worrying about any other advance configuration setting. For more advanced setup, please proceed to the next section. Important: After clicking on Connect, please be sure to “Save Settings” to register the username / password or any other changes. Figure 2 (Quick Start page) 4.
Figure 3 (Setup page) 4.3.1 Wide Area Network Connection On the other side of the ADSL router is where your Wide Area Network (WAN) connection; also referred to as a broadband connection. This WAN connection is different for every WAN provider. Most of the configuration you will perform will be in this area. 4.3.2 Local Area Network Connection On one side of the ADSL router, you have your own Local Area Network (LAN) connections. This is where you plug in your local computers to the ADSL router.
Since multiple users can use the ADSL router, the ADSL router can simultaneously support multiple connection types; hence, the user must set up different profiles for each connection. The ADSL router supports the following protocols: • DHCP • RFC2364 / PPPoA • RFC2516 / PPPoE • Static • Bridged • RFC1577 / CLIP . 4.4.1 New Connection A new connection is basically a virtual connection. The ADSL router can support up to 8 different (unique) virtual connections.
To complete the connection, you must now click the Apply button. The Apply button will temporarily save this connection. To make the change permanent, you need to click on Save Settings. At the system commands page, click on Save All. 4.4.1.2 PPPoA Connection Setup PPPoA is also known as RFC 2364. It is a method of encapsulating PPP packets over ATM cells which are carried over the ADSL. PPP or Point-to-Point Protocol is a method of establishing a network connection / session between network hosts.
Figure 5 (PPPoA Connection Setup) To complete the connection, you must now click the Apply button. The Apply button will temporarily save this connection. To make the change permanent, you need to click on Save Settings (at the side of the page). At the system commands page, click on Save All. 4.4.1.3 PPPoE Connection Setup PPPoE is also known as RFC 2516. It is a method of encapsulating PPP packets over Ethernet.
e. f. g. h. Keep Alive: When on-demand option is not enabled, this value specifies the time to wait without being connected to your provider before terminating the connection. To ensure that the link is always active, enter a 0 in this field. Set Route: Specify this connection as the default route. MRU: Maximum Receive Unit the A DSL connection can receive. It is a negotiated value that asks the Provider to send packets of no more than n bytes.
using 0,100. Also select the Quality of Service (QoS); leave the default value if you are unsure or the ISP did not provide this information. If your ADS L is connected and your A DSL Provider/ISP is supporting DHCP, you can click the renew button and the gateway will retrieve an IP address, Subnet mask, and Gateway address. At anytime, you can renew the DHCP address by clicking on the renew button; in most cases, you will never have to use this button.
Based upon the information your A DSL Provider/ISP provided, enter your assigned IP address, Subnet Mask, Default Gateway (if provided), and Domain Name Service (DNS) values (if provided). For the static configuration, you can also select a bridge connection or a routed connection. Since static IP address is typically used to host web servers, you may want to use a bridge connection. Figure 8 (Static Connection Setup) To complete the connection, you must now click the Apply button.
Figure 9 (CLIP Connection Setup) To complete the connection, you must now click the Apply button. The Apply button will temporarily save this connection. To make the change permanent, you need to click on Save Settings (at the side of the page).

The connections are listed as Connection 0 through Connection 7.
4.5.1 Enable/Disable DHCP To enable or disable DHCP, click setup. Under LAN Setup, select DHCP Configuration. This will bring up the page shown in Figure 10. The Start IP Address is where the DHCP server starts issuing IP addresses. This value must be greater than the ADSL router IP address value. For example, if the ADSL router’s IP address is 192.168.1.1 (default) then the starting IP address must be 192.168.1.2 (or higher). The End IP Address is where the DHCP server stops issuing IP addresses.
Figure 11 (Example of a DHCP Relay configuration) By turning off the DHCP server and relay, the network administrator must carefully configure the IP address, Subnet Mask and DNS settings of every computer on your network. Do not assign the same IP address to more than one computer, and the ADSL router must be on the same subnet as all the other computers. The Apply button will temporarily save this connection. To make the change permanent, you need to click on Save Settings (at the side of the page).
Figure 12 (Management IP) The Apply button will temporarily save this connection. To make the change permanent, you need to click on Save Settings (at the side of the page). At the system commands page, click on Save All. 4.5.3 Firewall/NAT Services You can enable or disable Firewall and NAT when you are creating a new Connection. By default, both NAT and Firewall are enabled.
To enable UPnP, you must first have a WAN connection configured. Once the WAN connection is configured, click Advanced and under Advanced, select UPnP. This will bring up the page shown in Figure 13. You must enable UPnP and then select which connection will utilise UPnP. In this case, the PPPoA connection is enabled. Figure 13 (UPnP ) The Apply button will temporarily save this connection. To make the change permanent, you need to click on Save Settings (at the side of the page).
For example, if you want to host a NetMeeting session, from the Home page, click Advanced and under Advanced, select Port Forwarding. First select the IP address for your NetMeeting server. Next, select the Audio/Video category and add NetMeeting to the applied rules box. To view the management rules, highlight NetMeeting and select view; this will display the pre-configured protocols and ports that NetMeeting will use.
Figure 14 (Access Control) The Apply button will temporarily save this connection. To make the change permanent, you need to click on Save Settings (at the side of the page). At the system commands page, click on Save All. 4.6.3.1 DMZ Configuration Setting a computer (on your local network) as a DMZ forwards any network traffic that is not redirected to another computer via the port forwarding feature to the computer's IP address. This opens the access to the DMZ computer from the Internet. 4.6.3.
4.6.3.4 Enable Incoming ICMP Ping Enabling the Incoming Internet Control Message Protocol (ICMP) Ping will allow Echo requests to come into the gateway. The gateway will respond with a ICMP Echo response message. The option allows the A DSL Provider or ISP to determine the following: a. The status of the network. b. Tracking and isolating hardware and software problems. c. Testing, measuring and managing networks. 4.6.4 Access Control Access control can also be called port blocking.
the “Apply” button. The “Select All” select box can also be used to delete the entire filter rule. It provides a quick method of selecting all filter rules for deletion. The “Enable MAC Filters” button allows the user to enable or disable MAC filtering. It can be set/unset during any add/edit/delete operation. It can also be set/unset independently by just clicking the “Apply” button. Figure 15 (MAC Filters) Note: The MAC filter table contains 3 hidden rules.
b. c. d. e. There are no restrictions on a host's location. There are no restrictions on the number of members that may belong to a host group. A host may belong to multiple host groups. Non-group members may send UDP datagrams to the host group. Multicasting is useful when data needs to be sent to more than one other device. For instance, if one device is responsible for acquiring data that many other devices need, then multicasting is a natural fit.
Mask is 255.255.255.0. The Gateway IP address should be the IP address of the gateway device that allows for contact between the Gateway and the remote network or host. The Hop Count determines the maximum number of steps between network nodes that data packets will travel. A node is any device on the network (such as a router or switch). To enable Static Routing, from the Home page, click Advanced and under Advanced, select Static Routing. Figure 17 illustrates a typical Static Route.
in RIP v2 format using subnet broadcasting. If RIP v1 Compatible is selected, routing data will be sent in RIP v2 format using multicasting. To enable Dynamic Routing, click Advanced and under Advanced, select Dynamic Routing. Figure 18 illustrates a typical Dynamic Route.

Before calling technical support, please look through these issues to see if they help to solve your problem. 5.1 The ADSL Router Is Not Functional 1. 2. 3. 4. 5. 6. 7. 8. 5.2 I Can’t Connect To The ADSL Router. 1. 2. 3. 4. 5. 5.3 Check to see that the power LED is green and the network cables are connected correctly. Refer to the Quick Installation Guide for more details.
5.4 The DSL Link LED Is Always Off 1. 2. Make sure you have a ADSL service. You should get some kind of information from your ISP that states that the ADSL service is enabled. You can usually tell if the service is enabled by listening to the phone line; you will hear some high-pitched noise. If you do not hear high-pitched noise, contact your ISP. Verify that the telephone cable is connected directly to the telephone wall socket and the DSL input on the ADSL router.
6. ADSL Router Terms What Is A Firewall? A firewall is a protection between the Internet and your local network. It acts similarly to the firewall in your car, protecting the interior of the car from the engine. Your car's firewall has very small opening that allow desired connections from the engine into the cabin (gas pedal connection, etc) but if something happens to your engine, you are protected. The firewall in the ADSL router is very similar.
or other network device where to send data if the target station does not reside on the same subnet as the source. If your machine can reach all stations on the same subnet (usually a building or a sector within a building) but cannot communicate outside of this area, it is usually because of an incorrectly configured default gateway.
