Hi, say I have two external IP addresses: 220.x.x.9 220.x.x.173 Is it possible for me to forward all the requests on an ethernet card (220.x.x.9) to another ethernet card (220.x.x.173) on different network? I am not sure if I can do it with PREROUTING - DNAT in NAT table. In my confusion, I thought it only supports external ip -> LAN ip/internal ip translation. Plus I don't have the proper hardware to test this out at home. Has anyone experienced this before? Any clues would be greatly appreciated. Thank you. Regards, Foo
