Hello all.
I have same problem:
I am trying to run a HLDS ( gold ) server behind NAT, but cannot manage to make it so people outside my local network connect to the server, can someone help me figure it out?
Server is runing on proxmox vm ubuntu and it has set static ip
server is running on udp port 27015. I manage to make a connection trough this port using netcat and send messages between vm and computer outside my local network, but still cannot connect to the server troug the game
