I have setup Wireguard on the router/LEDE and it working great - much better then OpenVPN. :)
 
But I cannot work out how to bypass the default route to allow one of my devices on the lan to bypass Wireguard route to allow netflix to work properly. I have tried the app "vpnbypass and that didn't work. I also tired similar app called vpn/wireguard policy routing and it didnt work aswell.  I'm using PPPoE on the WAN. I hope you can help me
