[SOLVED] PPPoE on a bridge, nat sees bridge as incoming interface

[Georgi Georgiev <chutz@gg3.net>]

My problem has been solved for a week now. Here is the summary.

Problem: If a PPPoE connection is initialized over a bridge the nat
table will see any incoming IP packet as coming from the bridge
interface, and not the ppp interface.

Solution 1: Set the following sysctl key to 0
net.bridge.bridge-nf-filter-pppoe-tagged

Warning: If adding this to /etc/sysctl.conf (or equivalent), make sure
that the bridge module gets loaded *before* sysctl is applied.

Solution 2: Compile the kernel without CONFIG_BRIDGE_NETFILTER.

Both of these worked for me. I'm sticking with number two.
