If you're having trouble port-forwarding, try this guide HEREGuide V1.2.3If you're not using a router, then forget about this thread.
If you don't know how to forward a port, this is for you!
(I'm not sure this method works or not but it works for me!)
1) Go to this site,
here!
2) Pick your router, if your router isn't there just pick the closest one.
3) For convenience, pick Utorrent when you're shown a list of applications. (Utorrent not required)
4) Ignore everything until you see this: Utorrent's Port for incoming connections.
5) Input 8190 into the box. Follow the rest of the steps shown on the web.
6) Note: GG2 only uses TCP, the ip in your address bar should be your dynamic(external) ip.
7) If you're to name your "port", name it GG2 instead of Utor1.
*You have to do this every time you restart your PC/laptop/router (for some).*
+To check your static(internal) ip, simply go to Command Prompt and type ipconfig.

2) Look for exceptions.
3) Look for Add Port.
4) Name: GG2, Port:8190, TCP

Note: 8190 is GG2's default hosting port, if you changed it, replace 8190 with your number.
How to check whether your server is working1) Open up 2 GG2s.
2) Host with a GG2, while checking whether it appears in lobby with another GG2.
