ANSWERED Port forwarding - port closed

[ohshitgorillas 0]

I have done quite a bit of searching but unfortunately most of these issues end up being related to Windows firewalls or some other thing. I am running everything on a headless linux server from the command line, and mostly using docker containers to manage these processes.

I have generated a wireguard config file, and can successfully connect to the server, however, the open port I was assigned is consistently closed. Transmission's internal port tester shows the port as closed, and using the tester on the website results in a "Connection refused" error.

• The service doing the listening is running when I do these tests.
• Transmission is configured to use the forwarded port.
• I restarted the connection after forwarding the port.
• Turning off my firewall (UFW) doesn't make a difference.
• This same setup worked flawlessly with mullvad (RIP)

Any other suggestions or ideas? I have two more days on my subscription to sort this out before I have to decide to keep the service or look elsewhere.

I have, but I figured it can't hurt to reach out here, too. If I find a solution, I'll post it so that maybe someone else in a similar situation might get the help they need.

I'm looking at the documentation and wondering if I need something similar to the iptables rules listed here enforced within the container? It's not DD-WRT, but it is a manual connection so it's similar.

I was able to resolve the problem by using "network_mode: service:airvpn" under the transmission settings in docker-compose.yaml. Previously I was using a bridged network to connect the two, but apparently it needs to share the entire network space with the VPN container.
