SMC Networks ADSL Barricade SMC7204BRA - Manual (Page 39)

Configuring the LAN Ports
34
If your network uses a DHCP server (other than the ADSL
Barricade) to assign IP addresses, you can configure the
device to accept and use a LAN IP address assigned by that
server. Similarly, if your ISP performs DHCP serving for your
network, you can configure the device to accept an IP address
assigned from the ISP's server. In this mode, the ADSL Barricade
is considered as a DHCP client of your DHCP (or ISP's) server.
Note: The ADSL Barricade itself can function as a DHCP
server for your LAN computers, as described in
Configuring Dynamic Host Configuration Protocol,
but not for its own LAN port.
Follow the following steps to change the default LAN IP address
or to configure the LAN port as a DHCP client:
1. Log into Configuration Manager and then click the [LAN] tab.
The [LAN Configuration] page appears.
