no it doesn't support pppoe passthrough for multiple pppoe sessions.
change the mss mangle on the ethernet to something like 1300 and everything will be fixed. We had the same problem.Hello Uldis,
I have deployed quite a few RB133c boards in router mode doing the PPPoE login and they are working great. I just have a problem with one customer that only happens when he is logged in as an administrator, on a certain website completing web forms. That is the only reason I am trying to bridge a PPPoE connection through the Rb133c. The website works when I use a bridge and PPPoE authentication from his wireless router. All my other customers are routed using the MT RB133c. I love this setup too by the way.
