Need Help Making CS:S Public Server

[CrazyAznPride]

I made my server on srcds and my IP is 192.168.1.100:27015

I have a router thats a linksys and the model is WRT54G.

My server can't go public.

I did everything on the http://www.portforward.com but my server still isn't public.

I need help making a public server.

Thank You
