what is an ip wan
The WAN (Wide Area Network) IP is the ip address associated with the outside-facing network port; whereas, the LAN (Local Area Network) IP is the ip address associated with the inside-facing network port.n this case, the LAN IP would be the ip address of the router with which your local network pc's communicate.
