What does an ospf debug show on the 2800 side? I've had issues before with DSL ospf and mis-matched network types due to the point-to-multipoint type of relationship you get with an LNS/client, does putting a /30 on the link make any difference? I think the debug is going to be the one that tells the story, if you don't even see hello's then you probably have something blocking it in between.

Marko, Would it be possible for a DSLAM to implement filtering on the AAL5 encapsulated traffic? It would have to decapsulate and interpret UDP/IP packets to do it. Did you experience anything similar? I would point my finger at a IOS bug, however I tried several completely different IOSes on both the termination and DSL box with no change.
