People still seem to have a hard time connecting despite gentool.
I suspect people still haven't forwarded their ports and set their static IP addresses in Windows.
Would it be possible to put these instructions on the online welcome screen? This way people don't have to google it, and we can be assured everyone follows the correct instructions?
I feel this is the natural place for this, and I'll gladly write up the instructions on setting a static (preferred) IP address, and forwarding the appropriate ports.
