My servers are set up like this:


TF2 Client (player) -> Tunnel server -> Game server
This masks the game server's IP.

Let's say the Tunnel Server's ip is tt.ttt.ttt.ttt and the game server's ip is gg.ggg.ggg.ggg

I can connect to the game server using the tunnel server's IP just fine (tt.ttt.ttt.ttt).
I cannot connect to the game server using gg.ggg.ggg.ggg, this is intended. I have not opened ports on this network.

However, the Game Server reports the server as:

Connection to Steam servers successful.
   Public IP to Steam is gg.ggg.ggg.ggg

And

https://api.steampowered.com/ISteamApps/GetServersAtAddress/v0001?addr=gg.ggg.ggg.ggg&format=json

reports my servers as running, while

https://api.steampowered.com/ISteamApps/GetServersAtAddress/v0001?addr=tt.ttt.ttt.ttt&format=json

does not report my servers as running.

This is because my game server reports its own public IP to steam.

Adding

+net_public_adr tt.ttt.ttt.ttt

or

+net_public_addr tt.ttt.ttt.ttt

doesn't seem to have an effect.
If I change

 +ip 0.0.0.0`

to

+ip tt.ttt.ttt.ttt

, I get this fatal error:

WARNING: NNET_OpenSocket: bind: Cannot assign requested address
FATAL ERROR: Couldn't allocate any server IP port

My startup command is this:

./srcds_run -game tf -console -port {{SERVER_PORT}} +map {{SRCDS_MAP}} +ip 0.0.0.0 -strictportbind -norestart +sv_setsteamaccount {{STEAM_ACC}}

How do I change it so that my game server reports the tunnel server's IP to steam, instead of the game server?
