Bridging and filtering traffic

Hi,

bridge-nf allows you to use iptables to filter Ethernet traffic in a bridge.

Can bridge-nf be modified to let me filter PPPoE traffic with iptables?

I would like to let all non-IP traffic to be bridged as normal, however if
there is IP traffic encapsulated within a PPPoE session, I would like to
pass the IP packet through iptables but still retain the original PPPoE
header so that after iptables, the original packet can be reconstructed
with the PPPoE header back in place.

Is there any way I can strip off any PPPoE headers and store them with the
packet for later use?

Any hints or directions appreciated!

Thanks,

Mike
