Android 13 ethernet tethering forward all ports

i want to forward the mobile Internet on my rooted Pixel 7 to my router. My router forwards ports 80/443 to a client in my local network to host some web services. I want to be able to forward the ports from my phone to the local client: **Internet** --5G (rmnet1)--> **Pixel 7** --Ethernet (eth0)--> **Router** --> **Client**:443 I have no GCNat in front of the Pixel 7. In fact i can forward non priviliged ports with the Fwd: port forwarder app and its working as expected Ideally all ports would be forwarded to the router as i also want to use Wireguard. I would also be happy if the phone is only working as a dumb modem, bridging the two interfaces. I already tried the answers here and here , but requests always timed out.
