Hallo,

i have some throuble using my c877 with he.net.

I've setup ipv6 over a tunnel interface, i can reach ipv6.google.com and http://www.whatsmyipv6.com gives me back the correctly routed ipv6 but i cannot reach he.net (i can reach it only using ipv4).

That's the traceroute to ipv6.he.net

Code: [Select]

Type escape sequence to abort.
Tracing the route to ipv6.he.net (2001:470:0:64::2)

Is that solvable?

Some host/router block icmp.
This might be the case. But that should not make a difference for http protocol.
Try: telnet he.net 80

Hallo,

how have you configured the /48 for use on your system? details and pastes please

I note that the above traceroute does show that packets are leaving his machine with the tunnel and are coming back, so I don't think that's the problem.

It looks as if hop #7 is blocking ICMPv6 (being a peer of the Fremont router, hop #6).

Actually looks like by default we drop udp traceroutes at the host, but traceroute6 -I ipv6.he.net or mtr or ping6 should all be working.
