i am trying to host a public server to play on using the 14.8 server headless files on a xubuntu 16.04.01 install using pfsence router with port 34197 forwarded to the server i have static ip on the server and it does list in the mplayer list but not able to be joined by any one unless conected directly from the dedicated ip the issue lies with the routers nat for the matching servers ... this i am aware is there a dedicated port the matching server use as ever time i set the port forwarding the matching server change ports like it dosent want a dedicated port being used??
