I am trying to configure a workstation (that has 2 NICs) to have one NIC with an address of (let's say) 150.150.150.1 and another to have an address of (let's say) 150.150.149.1. The reason I'm doing this is because I am building a test bed and will be putting a firewall on this workstation. I am essentially making this workstation a router for my testbed. But how do you configure the 2 NICs on the one machine for different subnets?
