In-kernel pppoe has the problem of missing "MSS clamping" for forwarded
connections AFAIK. This was the reason for using rp-pppoe instead of the very
well working mouse-pppoe for me.

Are there any success stories about this? I never really tried this out, as it
was documented, that the correct MSS is only sent in outgoing connection from
the interface, not in forwarded connection via a firewall using pppoe0.
