I have two NIC's in the machine, so I would like for the "server" to be reachable over either interface. To my mind, I would give a loopback interface an IP address that is the "server" in this case. Then, each interface would have it's own subnet and I would route over those two interfaces to the loopback for all packets destined to the server. So, something like: lo1 -> 192.168.1.1/32 ed0 -> 172.16.1.2/30 ed1 -> 172.16.1.6/30 Then, on the router, I have a route statement for 192.168.1.1/32 over the two interface subnets. Is this possible?
