SSG 20 Hardware Installation and Configuration Guide

Static IP Address and Netmask

If your service gave you a specific, fixed IP address and netmask for your network, then configure the IP address and netmask for the network and the IP address of the router port connected to the device. You need to also specify that the device is to use the static IP address. (Typically, the device acts as a PPPoE or PPPoA client and receives an IP address for the ADSL interface through negotiations with the PPPoE or PPPoA server.)

You need to configure a PPPoE or PPPoA instance and bind it to the adsl1/0 interface, as described in “PPPoE or PPPoA” on page 43. Make sure that you select Obtain IP using PPPoE or Obtain IP using PPPoA and the name of the PPPoE or PPPoA instance.

To configure the static IP address 1.1.1.1/24 for the network, use the WebUI or CLI as follows:

WebUI

Network > Interfaces > List > Edit (for the adsl1/0 interface): Enter the following, then click Apply:

IP Address/Netmask: 1.1.1.1/24

Static IP: (select)

CLI

set interface adsl1/0 ip 1.1.1.1/24 set pppoe name poe1 static-ip save

or

set interface adsl1/0 ip 1.1.1.1/24 set pppoa name poa1 static-ip save

To use Domain Name System (DNS) for domain name and address resolution, the computers in your network need to have the IP address of at least one DNS server. If the device receives an IP address for the ADSL2/2+ interface through PPPoE or PPPoA, then it also automatically receives IP addresses for the DNS server(s). If the computers in your network obtain their IP address(es) from the DHCP server on the device, then the computers also obtain these DNS server addresses.

If you assign a static IP address to the ADSL2/2+ interface, then the service provider must give you the IP address(es) of the DNS server(s). You can either configure the DNS server address on each computer in your network or you can configure the DHCP server on the Trust zone interface so that it provides the DNS server address to each computer.

To configure the DHCP server on the bgroup0 interface to provide the DNS server address 1.1.1.152 to computers in your network, use the WebUI or CLI as follows:

WebUI

Network > DHCP > Edit (for the bgroup0 interface) > DHCP Server: Enter 1.1.1.152 for DNS1, then click Apply.
