Well my server was working fine. But then i couldnt connect as admin anymore, so i tried 192.168.0.3 (0.2 being previous), and i could connect, weird, now nobody can join, so i tried prot forwarding to 0.3 and its not working.
What do i do :O

here is what you do.

Find out your internal IP of your server. It should be 192.168.2.XXX

(If you have windows as your soldatserver, goto start run, type in cmd, then ipconfig)

after you found out your internal ip, go to your routers ip (should be 192.168.0.1 or 192.168.2.1) and goto virtual server, and just forward the ports there
