  Can you ping6 2001:470:1f10:b8f::1 (i.e., what should be the HE side 
of your tunnel) with any regularity?  I'm attempting to trace to 
2001:470:1f10:b8f::2 to no avail.  You're not filtering IPv6 traffic 
(with ip6tables), are you?  (Wait, if you're behind NAT, is the NAT 
device forwarding protocol 41 to whatever computer/device is terminating 
the tunnel?)

  I'd be happy to follow up on this; HE has specifically asked me to 
help others complete the certification.
