Although virtually every wireguard how-to tells you to configure prefixes on the wireguard tunnels/interfaces they are in fact not required at all for wireguard to function. You can configure them if you need them as a route target (to route traffic into the tunnel) but otherwise I prefer to just leave them away.
What's important are the "Allowed IP" fields. Make sure they contain the prefixes you want to make it through the tunnel. If wireguard sees a package with a source IP that's not listed here it will just discard the packet.
