Thanks, but I have configured a dedicated IP range for my Wireguard network, so the devices have IPs like 10.0.0.1. But I still want to access services in my home network in the IP range 192.168.178.0/24.
And in your example the AllowedIP = 192.168.178.2/32 of the VPS would still make it possible to route traffic from my smartphone via the VPS to my home server?
