Suppose ip forwarding works.
not sure what you mean, but will take a stab if you had A) eth0 192.168.1.1/24 gw 192.168.1.254 B) eth1 192.168.2.1/24 gw 192.168.2.254 you want something like ip r a default via 192.168.2.254 src 192.168.1.1 so this say's all applications that attempt to open a socket without binding to and address will get 192.168.1.1 (NIC A's address), but will route out NIC B not sure if it will work, might take a bit more work > > > Just out of curiosity, does anyone know how iPhone restricts VOIP traffic > over 3G technically?
