Hosting a dinosaur survival game on a Linux box: the networking step that beat me

Tariq Vos · 2026-09-16T00:53:36.213Z

im literally losing my mind here im tearing my hair out... my a dinosaur survival game server on a Linux box works locally, but my friends server list shows nothing. I forwarded TCP 25565 and still got this on teh host when I checked the network: [code] Any ideas before I give up and rent a server? I'm reasonably techy, but networking is not my strong suit. I'd appreciate a checklist of what usually goes wrong, so I can go through it step by step.

```
Network & internet
Wi-Fi  •  HomeNet_5G
No internet, secured

Connected, but nothing loads. Troubleshoot problems?

port checker sites often report UDP ports as closed even when they work, because UDP has no handshake. test by having a friend connect directly with your public IP and port instead.

Allow teh server through teh host firewall. On Windows: New-NetFirewallRule -DisplayName "Game Server" -Direction Inbound -Protocol UDP -LocalPort 27015 -Action Allow (adjust protocol and port). on Linux with ufw: sudo ufw allow 27015/udp. fingers crossed 🤞
