I successfully run 4 game servers (latest versions of Urban Terror, Unreal Tournament 2004, Xonotic & Warsow) that I can connect to with a client from the LAN and WAN by ip.
Since I changed server OS from ClearOS to initially NethServer 7, I am having problems getting listed.
Because someone advised me to solve this problem the easiest way, I changed to the Hypervisor Proxmox and now I am running the game servers in Debian 12 based containers with a dedicated OPNsense firewall box.
Because I do not encounter this problem with UT2K4 I must assume that it's not something simple like a problem with portforwarding, because those are identical.
But with the Urban Terror, Xonotic & Warsow it's only possible to connect from the Internet by ip address and not with the in-game- or online listings.
I already tried every trick in the book that I could find, but nothing works with these 3 games.
https://arena.sh and https://www.urbanterror.info also reports that the servers are unreachable.
The only problem I have with UT2K4 is that I can't figure out how to add my server to GameTracker.com.
For unknow reasons it reports that one of the following criteria is true:
- Server is not online
- Entered the wrong Query Port
- Server is firewalled
Could it have something to do with a setting in OPNsense ... ?!?
Please advice,
Mister J.
