Well, I got this fun routing problem again; so here it goes. I have a router, which gets native ipv6 on xl0 with block 2001:a6x:2:1x::/64 and she has also lan-interface. My idea was to route 2001:a6x:2:1x:dead::/96 to lan interface so i thought doing as follows; added 2001:a6x:2:1x::3/64 to lan-interface, then routed 2001:a6x:2:1x:dead::/96 to it. Now the fun comes in, xl0 pings net fine, lan interface pings xl0 fine, but lan interface wont ping net. tcpdump says like this: 13:13:32.755545 2001:a6x:2:1x::1337 > 2001:a6x:2:1x::: icmp6: echo request 13:13:32.764543 2001:a6x:2:1x:220:48ff:fe5b:2d15 > ff02::1:ff00:1337: icmp6: neighbor sol: who has 2001:a6x:2:1x::1337 no answer. so gw-router is like "hmm. who the fck has this address." then asks it with multicast or similar thing (ff02-thing) but wont get reply? Why lan-if wont get that multicast-whateveritis request while it is on same net but different interface? all forwarding sysctls are 1. no firewalls harrassing or anything. Greets Markus Kovero
