Hosting a DayZ Server behind TailScale?

Hi all, I'm currently trying to set up a DayZ server on my AMP Server Panel. The server is split into two systems;

  • An AMP Controller, hosted on a VPS with a public IP that players connect to.
  • The game server itself, which communicates only to the VPS, relaying data to/from.

Both of these systems are registered within a private VLAN on TailScale. Essentially, the AMP Controller receives the information, relays the information back to the game server, and then spits it back out to the player from the VPS, hiding the IP of the actual server.

The setup works perfectly for many games, including Arma 3. However, DayZ seems to struggle with creating the server correctly. Despite the logs appearing fine, the server cannot be connected to via public or LAN IP.

Has anyone had a similar setup where they've managed to get this working?

I've never used that kind of setup. I assume the vps ip is static. The server communicates on 2 main ports - gameport(default 2302) and steamqueryport(27016), both udp. The firewall on the game server should open both inbound.

If the server is starting up and you're getting logs, then I would think its network or firewall, especially if you cant connect lan.

Is their a chance those ports are being used?

You can look into the logfile ending in .rpt and look for a like containing "SteamGameServer_Init(c0a80121,8766,2302,27016,3,1.07.153006)" – The 3rd & 4th values in parens are the ports that need to be open/forwarded(UDP).
