cs with dl router

[raiden_nrl]

I have a dl 604 router and it alows me to play counter strike but i need to set it up so i can run a server with the router. The router gives me the default 192.168.0.1. So oviously no one can connect to my server. I know in the administrative part of my router i can allow ports to be accesed but how can i find out what counter strike is using. I want to allow counter strike full access to the internet so people can connect to me. Thanks for the help.

it says my server IP is 192.168.0.100 i think that means only people on my LAN can join even though i opened those ports
