Gateway set up

The following example will focus on the most common gateway setup: an Ubuntu computer with two wired network adapters (eth0 and eth1) hosting ICS to a static internal network configured for the 192.168.0.x subnet.

For this example, eth0 is used to represent the network card connected to the Internet, and eth1 represents the network card connected to a client PC. You can replace eth0 and eth1 as needed for your situation. Also, any private IP subnet can be used for the internal network IP addresses.

In summary:

eth0 = the network adapter with internet (external or WAN).
eth1 = the network adapter to which a second computer is attached (internal or LAN).
