When i try this the CPE gets stuck on “Dialing…”, I Can Ping 10.0.0.1 from my CPE and access the box as normal but i just can get a PPPOE link, However if i bridge the ROUTERs 2 interface like so
You can get this easily working if you create EoIP tunnels from your APs to your PPPoE-AC. No need to go back to bridging just to be able to offer PPPoE via a central AC…
