I ran into such a problem.
I use the source code Infestation: Last Survivor Source
When I had a local IP I did not have a try, but when I changed to another that would play around with friends there was such a problem that the friend does not look for the server, but I'm fine, I thought the problem in ports and decided to change them to standard ones, and now I can not even find the server.
