RE: IPv6 return path filter default active?

[Reinier Boon <R.Boon@telecats.nl>]

Hi,

	I haven't find any resources about rp_filter and IPv6.

No, there does not seem to be such a filter, which is why I do not understand what is going on.

	Did you simply check that /proc/sys/net/ipv6/conf/all/forwarding was set to 1?

:-) Yes, but that is not the problem. Router A does route incoming traffic, only blocks traffic originating from itself (or coming though it) that returns on a different interface than it was sent on.
I just cannot find a mechanism that would block this traffic, other than a firewall. But if I switch off my firewall, the traffic is still blocked...
