Maybe snag a tcpdump of the l2tp traffic.  Should be able to run tcpdump
on the ethernet interface specifying only traffic to/from the LNS IP
address.  If you wanna tell tcpdump to write the traffic out to a file,
you can then pull it up in ethereal and be able to look at just about
everything with the traffic and see what's going on.  That'll at least
give us an idea of what its putting out on the wire, which might give us
and idea of what's going on without digging into the code too much.  :)
