www.ripe.net unreachable over ipv6

[ewr]

Greetings.

My English is not very good, excuse me, if I said something wrong

Just created new tunnel. All seem works properly, ipv6.google.com reachable. But since ipv6 activated on my home computer, www.ripe.net site become unreachable at least from mozilla browser. I can reach this site only if disable ipv6 DNS resolving. What could be the reason? Maybe I did something wrong?

'mtr -6' to ww.ripe.net

I don't have any problems browsing to or pinging ripe.net

I am using the same tunnel server, and I don't see the problem. I do see a few intermediate routers, that don't respond, but the final destination does respond. I suggest you try again.

I did recently see some similar symptoms recently, that turned out to be caused by a bug in mtr. I suggest you try using an ordinary traceroute command as well to verify if it shows you the same results as mtr.

I tried the same and it looks like everything is working fine here too.

The same here.

To state it more exactly, I can access all the servers (including HE IPv6 and RIPE) from "Client IPv6 Address", which is in my case 2001:470:6e:128::2/64, but from "Routed /64", i.e. 2001:470:6f:127::/64, I can not access www.ripe.net and IPv6 HE servers, though I can ssh to and from a non-HE IPv6 network to this routed segment, where the machine running IPv6 tunnel to HE is acting as a IPv6 router.

Tested with OpenBSD and Linux, each as server (tunnel+RA+router) and client trying to access www.ripe.net through the server. Ping6 to HE and RIPE machines works always.

I just hit http://www.ripe.net/ from part of my routed /64 (not from the tunnel endpoint), and got to it just fine and it reported my ipv6 address on a little widget on the page.

I've also always been able to hit all of the HE servers as well from my routed /64.

If you can ping, but can't get a web page, that almost sounds more like a firewall issue, but that's just a guess without more info.

Of course it was an MTU problem, because I am tunnelling through DSL.
