issues matching players between private and public networks #106
Description
Hi. I've been trying to allow matchmaking between players from a private network (the server is hosted here and at least one client lives here) and players on external networks (i.e. external players connecting to the server).
However, when both players are connecting to the server and matchmaking begins, the following occurs:
Server (Network A) logs in Player 1 who is also in Network A. Server reads Player 1's private ip (e.g. 192.168.0.10). The Server and Player 1 technically both share the same public IP.
Player 2 logs in from another network and server reads Player 2's external, public IP (e.g. 123.456.789.123).
When the matchmaking starts, the Server is passing on Player's 1 private IP to Player 2, who is not able to connect to this IP. This behavior is confirmed through wireshark, where Player 2 is continuously attempting to connect to private IP 192.168.0.10. In order to allow this connection the server would have to pass Player 1's public IP (or the server own's public IP) to Player 2.
Are there any workarounds recommended on this from the server side? Any and all input would be appreciated.
Server version: 1.4.2 on linux
