| |
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.
