Hi all.
I have a DSL router configured as a layer 2 bridge and directly connected to it is a Cisco 831.
I would like to have the Cisco 831 running as a PPPoE client for the DSL connection and NAT for my LAN.
However, I cannot get my configuration to work.
When I place a Linksys WRT54G behind the bridge, it connects via PPPoE with no problems but I would really like to place the 831 on the outside of my LAN.
debug pppoe events on the 831 (directly connected to the bridge) shows the following repeating loop:
Mar 31 : Sending PADI: Interface = Ethernet1
Mar 31 : padi timer expired
Mar 31 : Sending PADI: Interface = Ethernet1
Any help debugging the bba-group, vpdn and interface configurations would be very appreciated.
