Hi, I have exactly the same problem like "Zuendapp"

_Hello!

yesterday I set up the Wireguard plugin. I was previously running a native Raspbian OS with Wireguard (natively, not in a Docker container).
I configured the tunnel so that each site (a second Rasperrypi at a remote site as a client) could connect to the different networks on the other side and vice versa! This worked perfectly.

With the HomeAssistantOS Wireguard addon, I have the problem that my other clients (on the same network as the HAOS RaspberryPi) at one site can no longer reach the other remote site (from the server side to the client site). On the other way (from the server to the remote site) and with my remote devices (notebook, iPhone) it works fine....._

Can this be solved?
Thank you in advance.
