Does anything else external work?  Does any other traffic aside from ICMP work?

[BMSI]

Everything ip4 works.  No other ip6 traffic works either.  For example,
# host google.com 2001:470:20::2
;; connection timed out; trying next origin

[cholzhauer]

What are you using for DNS servers?  I guess my specific question was if you could visit IPv6 websites.

[BMSI]

# telnet ipv6.google.com 80
Trying 2607:f8b0:400c:c02::63...


It's as if my /64 subnet were not routed.

[cholzhauer]

Email ipv6@he.net and have them look at the routing.

It's as if my /64 subnet were not routed.

Which /64? I see four tunnels registered with your username, and all four are responding to echo requests from me.
