TrueNAS SCALE as Wireguard Client with app access

Hey all,

I’m trying to make my truenas scale apps available on the go via wirguard.
My wirguard setup works fine I can ping in both directions between my truenas machine and my offsite server. Also netcat on port 9002 works.
Somehow I’m only able to access Plex and not other official services (like minio).

I have both services (Plex and minio) running and can access them fine at the truenas server’s ip in my local network.
However via wireguard I can only access Plex (:32400) not minio (:9000&9002).

When I check with netstat -tulpen I also only see the Plex ports listed not the minio ports.
I suspect this has to do with the routing setup by k3s, but I couldn’t get a hot trace how to make it work for me.

I found this post in the old forum with exactly the same issue and no response:

Any help and tips are appreciated.
