i don’t know if my issue is related to OpenHAB and have no idea how OpenHAB should cause the issue, but I have even less of an idea of how my other services should cause it :).
The issue itself is simple: If I connect via VPN (OpenVPN) I a not able to access it.
Every other device in the network is perfectly reachable.
Every other service running on the same server behind a different port is reachable (no matter if its inside a container or not).
Just OpenHAB acts like it did not exist behind 192.168….:6444 (network timeout for the web frontend).
From within the network, everything is fine.
x64 machine with Debian bullseye
OpenHAB running the stable 3.4.4 Docker image
Docker CE 5:24.0.4-1
OpenVPN AS 2.12.0 (not running inside a container)
Just access to the network via NAT (192.168.154.0/24).
The Network-Related part of the docker config:
