Which reminds me - I think we should change them to default to off, they regulary break things for unsuspecting users. I'm not sure though what the best way to warn people for a while would be, feature-removal-schedule doesn't seem approriate. > This patch should make them work. > > bridge: Fix handling of non-IP packets in FORWARD/POST_ROUTING > > Currently the bridge FORWARD/POST_ROUTING chains treats all > non-IPv4 packets as IPv6.

Hi: It turns out that even though we have sysctl's that's supposed to control pppoe/vlan processing, they don't actually work. This patch should make them work. bridge: Fix handling of non-IP packets in FORWARD/POST_ROUTING Currently the bridge FORWARD/POST_ROUTING chains treats all non-IPv4 packets as IPv6. This packet fixes that by returning NF_ACCEPT on non-IP packets instead, just as is done in PRE_ROUTING. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Cheers,
