Hi, All, So far, all the applications I have seen for Iptables are focusing on connecting a WAN with one IP address to a LAN and using NAT. My question is if the iptables support multiple IP address on WAN side? If so, how it works (you only have one NIC on WAN side)? Is static NAT (it might not be the right term, I mean a static and permanent connection between WAN IP address and LAN IP address)
