[Kirby]

WEll im running my own server, i went through about 5 different guides, i did all the port forwarding, however, the server doesnt show up on steams masterlist of servers. Therefore, no one joins. HELP?

i have found that with my router its all about the filters in the configuration. mess around with them. also my server doesnt show up on my server list but people still join and they say they saw it on the list.

when you join your server try this. open your console and in the right top corner in whiteish letter you should see a few things they include the build # and the server IP. what does the IP say when you do this? is it your internal or external?
