For some reason, I am unable to broadcast on port 16043 at the moment. Therefore games of ChessWar XV F are currently broadcasted on chesswar.dyndns.org port 16045.
Be sure to open port 16045 in UDP mode in your router and/or firewall.
I don't know yet if this change is temporary or definitive, since I have no clue what happened to port 16043.
More information on how to connect and join the chat can be found on the ChessWar website.
