How to make WireGuard Firewall settings "stick"?

UPDATE: I went this route instead of using the GL GUI.

Wireguard with split tunnel

I solved my issue, but could not do that via the GL gui. I’ll give my solution here, as others might look for the same. Go to “MORE SETTINGS” → “Advanced” and log in Hover over “System” and go to “Software” Search for “luci-proto-wireguard” and klick “install” Hover over “Network” and go to “Interfaces” “Add new interface…” Choose a name for the Interface Select “WireGuard VPN” as protocol Make WireGuard Settings like in the GL gui As allowed IPs choose the Range of the remote network and add…

It resolved my issues.
