Ok, I've set up my router for IPv6 support (everything work at last: routing, prefix announcements, firewall, which allows ping but not access computers in my LAN from outer world, etc), double-check all configs and reboot router to be sure, that everything will work in case of reboot (that all manual changes are reflected in configuration files). Router boots up, all interfaces and firewall are Ok, gif0 interface is up. But for first 5 minutes IPv6 is useless! It can not even ping6 its own end of HE tunnel (bind to gif0)! Echo requests are sent, but no replies. It can not ping other end of tunnel, Goolge's IPv6 addresses, it can not be pinged from outside, etc. I've panicked, but about 5 minutes later everything works! Fully-functional IPv6 router, everything can be pinged, tracerouted, I can connect to outside IPv6 hosts, I can ping internal hosts from outside, etc. I've repeated reboot -- result is the same. 5 minutes router ``doesn't support'' IPv6, everything works after 5 minutes without any changes in configuration from my side. Is it normal? What do I do wrong? I'm sure that it is not firewall problem, as after these 5 minutes "deny" counters of my firewall are almost all zeroes -- only my ISP local network (IPv4) protection shows dropped packets (it has many script kiddies and zombie systems in local network, so it is not surprise me).
