Hi
Whatsmyip gives you the External Internet IP given to you by the ISP.
The IP of the Router is a local IP established by your system.
These are two IPs have different numbers.

The External IP is needed by people to connect to your server through the
Internet.
The Internal IP of the computer is needed if you Host locally or for Port
forwarding.
Most game sites explains how to host the game through a Router. It is
usually a matter of open the few ports that are used by the game.
If your Router is doing the ISP’s connection’s Authentication the Internet
might not work when the computer is directly on the Modem.
