The title pretty much explains it all. Now, it's kind of weird;
The ping is not ---, it's usually 1-20. I can join the server, but it's forever stuck on "CONNECTION ACCEPTED"
Connecting via Steam
and regular .exe both result unsuccessful.
The port I use is custom-set to 30000, because that's what I use for my port on my router. (It's a NETGEAR WNDR3400v2)

This is what happens in the server console when I join:

It just keeps spamming that until I disconnect.
Please help.
