I've been using the kernel support for pppoe since before it was actually
included in the standard kernel tree, and the mss clamp module for
iptables since it was introduced as well with great success. the setup is
rock steady, and the clamp module fixes the stupid path discovery issue
endemic to so many brane-dead dsl providers. note, that pppd also must be
patched to take advantage of this kernel support, and it is not available
in the standard debian package, although downloading the package source
and including the appropriate patch is pretty straight forward.
