I've got a PPPOE DSL line coming into my house, and I and my roommates
each terminate our own connection and get our own dynamic IP address.
With the recent bunch of viruses/worms, a couple of us were thinking
about setting up a box as a transparent firewalling bridge. The only
tricky bit is that we don't want to terminate the PPPOE connection at
that box, since that would then force us to do NAT/ipmasq.
Does anyone know of any way to filter the contents of a tunnelled packet
(PPPOE in particular) using standard tools like ebtables/iptables?
The other possibility I had considered was a netfilter module that tied
into the ebtables hooks and knew how to look inside the PPPOE packet,
but then I wouldn't get the userspace interface from ebtables/iptables.

So how is this question related to either
1) network development (netdev@oss.sgi.com)
2) linux-kernel development (linux-kernel@vger.kernel.org)
I would like to ask you this question at an apropriate mailinglist
(netfilter@lists.netfilter.org, or the lartc mailinglist [since the
assumption that you would need to do NAT in case you terminate the two
dsl lines is invalid an can be solved using policy routing + connmark]).

Sorry, my bad.
Thread continued on other list as suggested.
