Configure the Trusted Network

By default, the SOHO 6 uses DHCP to assign addresses to computers on your trusted network. In other words, every time you connect a computer to the SOHO 6, either directly or through a hub, it automatically attempts to obtain its addresses from the SOHO 6. If you use a cerntralized DHCP server to hand out IP addresses, the SOHO 6 has a DHCP Relay feature that forwards the DHCP request to the specified DHCP server.

Configure DHCP Server and DHCP Relay

To configure DHCP server:

1With your Web browser, go to the System Status page using the

Trusted IP address of the SOHO 6.

For example, if using the default IP address, go to: http://192.168.111.1

2From the navigation bar on the left side, select Network => Trusted.
