  I'm with Frank on this one: ICMP yes, HTTP/HTTPS no, via native IPv6 
(multiple locations).  No, wait -- it shows as open from a couple 
tunnels (both HE & SixXS).  So it's not consistent.  Lovely.

  Closed from:
2607:ff50::/32 (native)
2607:fcd0::/32 (native)

  Open from:
2001:1938::/32 (SixXS tunnel)
2001:4978::/32 (SixXS tunnel)
2001:470::/32 (HE tunnel)

  That gives me a really bad feeling of what might be wrong, but I'll 
leave it to the professionals.
