I have correctly port forwarded my server (people can connect) however, only 1 person can connect. The second/third will get booted as they try and join, saying that their connection has been "forcibly closed by the remote host".

I had a feeling it was a firewall issue, so I allow the UDP/TCP for 22565 for my traffic; doesn't work. I allow java to access my network; doesn't work. I disable my firewall; doesn't work.

Any potential fixes?
