Another 'Can't connect' thread

As in almost every thread in this section:
I’ve set up srcds, and everything works, except of course that the server is LAN. I can’t get it on th internet. Yes, the ports are forwarded correctly. To find my ip i went to whatismyip.com, as ipconfig in cmd doesn’t work. Sv_lan is set to 0. I’ve tried “Connect ip” in console in Garry’s Mod. As you probably guessed, nothing worked. Did i miss something?

EDIT:
How funny.
Going to the website on this computer, gives me the same output as on the server computer. (its the WAN IP).

Router maybe?

Router what?
