The issue I'm having seems to have been brought up a few times before, but the others didn't post sufficient information for the SRCDS wizards to help.

The problem I'm having is with other people trying to connect to my server, and for my server to show up in the Steam game list. When I give people the external IP address, the console tries 4 times, but is unable to connect. Is this a simple stupid-error on my part, or are there more complicated issues here?

Any help that you guys can give would be great.

Thanks,
Wes

Have you tried with windows firewall off?
