This is strange, I have configured the Nokia ONT(G140WF) to bridge on LAN Port 4, which connects to my OpenWRT Archer C-20 running YATE for Airtel's VoIP calls. I have had no issues whatsoever when connecting to the SIP system, but configuring PPPoE on the Archer fails with the PPPoE Active Discovery Packets getting lost. Anybody has a hint of what's wrong?
