I have an odd setup in that my qbittorrent client goes through a my own VPN and the VPN does port forwarding so the qbit client is reachable. VPN is set up on pfsense firewalls and container IP is configured to go through this.
I have migrated from docker to kubernetes on truenas but what i have found is that even using the latest image from here that port forwarding will not work on the BT Port. It works fine if its configured on anything other than for BT. E.g if i change the BT port to something else and then change the web port to use the port forwarded BT port it is reachable remotely.
From doing a tcpdump on the truenas host i can see the traffic going into container but it does not reply if with an ACK it replays with a syn/ack.
result and capture of port open test.
tcpdump on remote host checking port.
As the BT port responds normally when tested from Lan does anyone have any idea whats going on here. why does it not respond as expected.
