How to route WiFi to ADSL on a bintec?

I have a bintec RS230aw (ADSL + WiFi) router, and clearly I have no idea what I’m doing.

  • The ADSL connection is configured and working. I have network connectivity when I connect to the ethernet ports.
  • The WiFi connection is ok too, I can join the access point.
  • However, I have no Internet access from the WiFi.

I suspect I need to route WiFi trafic, but I’ve no idea how to do it.

Here are my current routes (the default ones) :

My WiFi configuration is :

, so there seem to be a route for the bridge interface already. What am I missing ?

Bonus question : by default, the Physical Ethernet Port of the WiFi is ETH1. I am connected to the ethernet port 1. Can this be a problem ?
