Back-to-Home + Starlink + KNX

Hi everyone,

I want to check if someone’ve already faced issue with KNX connection trough its software on standard udp port 3671 by VPN though Back-to-Home and Starlink connection.
Trough VPN I can ping the device, can reach by WebGUI by HTTP, but with the software that use that port not. I have also another device, fire prevention system, that use instead TCP 7090 that I can’t reach it too, but I can ping it.
For testing purpose I also disable all firewall policy, but I’ve got the same result.
Anyone has facing this issue with something similar?
