WatchGuard Technologies SOHO 6.1 instruction

Chapter 4: Configure the Network Interfaces

2Enter the IP address of the DHCP relay server.

3Click Submit and reboot the SOHO 6 as necessary.

The SOHO 6 will now send all DHCP requests to the specified, remote DHCP server and relay the resulting IP addresses to the computers connected to the Trusted Network. If the SOHO 6 is unable to contact the specified, remote DHCP server in 30 second, it will revert to using its own DHCP server to respond to computer on the Trusted network.

Configure additional computers on the Trusted Network

The SOHO 6 accepts connections from up to four computers. Network a larger number of computers together using one or more 10BaseT Ethernet hubs with RJ-45 connectors. The SOHO 6 system coexists with other systems over the same LAN (Local Area Network). If you mix computers with different operating systems on your network they pass traffic through the SOHO 6 to access the Internet.

Follow these steps to add one or more computers to your Trusted network:

1Verify that each additional computer has an Ethernet card installed. Shut the computer down, connect it to the network the same way you did in “Cabling the SOHO 6 for more than four computers” on page 20. Restart the computer.

2Set the computers to obtain their addresses using DHCP. For instructions see, “Enable your computer for DHCP” on page 16.

3Turn off and restart each computer.
