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! -- Best regards, Reinier Boon ________________________________________ Reinier Boon | Senior software engineer | Telecats bv | KvK Enschede 06069106 | Tel: 053 488 99 26 | Fax: 053 488 99 10 | Email: [email protected] From: Igor FLEDERICK [mailto:[email protected]] Sent: 07 September 2012 07:19 To: Reinier Boon Cc: [email protected] Subject: Re: IPv6 return path filter default active? Hi, Have you finally found a solution to your problem ? On Tue, Aug 21, 2012 at 8:46 AM, Reinier Boon <[email protected]> wrote: 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... -- Best regards, Reinier Boon Reinier Boon | Senior software engineer | Telecats bv | KvK Enschede 06069106 | Tel: +31 53 488 99 26 | Fax: +31 53 488 99 10 | E mail: [email protected]
