I'm working in a project: a Half-Life Dedicated Server in a DMZ. I'm using virtual machines under Virtualbox.
The network has two subnets, DMZ(Orange) and LAN (Green)
The DMZ has two servers, the main server (which has the HLDS program) and a secondary server which runs some network services, like a web server, DNS, etc.
The secondary server works perfectly and can be used all it services.
The problem is in the main server. It answers ping requests but I can't see the game rooms from the LAN computers.
What ports or forwarding must I add to the firewall rules? I also want the game can be accessed from RED net.
The server ports are these: https://developer.valvesoftware.com/wik ... ted_Server
but I'm note sure the client ports (Perhaps? https://portforward.com/half-life-steam/
Can you help me, please? Thanks.
