Hello,
Firstly, please check your Firewall zones on RUT241 and ensure that traffic from WG zone is allowed to LAN. Edit WG zone and add LAN to ‘Allow forward to destination zones’.
Also, make sure that your UNIFI has a route to the RUT241 LAN via WG.
It seems that you also want to split WG traffic on RUT241. If so, please take a look at this post here.
Kind Regards,
