RE: IPv6 return path filter default active?
Hi Igor,
No, not yet, but I must admit that I have not been able to spent time on this issue...
I am busy implementing VoIP solutions now ;-)
But still, it puzzles me which layer could block this return traffic coming from a non-expected interface. I would be glad to hear if anyone has an idea!

Hi,
Have you finally found a solution to your problem ?

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...
