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.
