=>route -n add -inet6 default 2001:470:1c:7e0::1

   I'm not on EC2, but I am on Xen and HE. My /etc/ifconfig.gif0 includes:

!route add -inet6 default ::1
!route change -inet6 default -ifp $int

so you might want to try that. Also, double check that your HE
tunnel is configured for the right IP address. If you think it
isn't, they have a service to automatically update it by visiting
a URL from your endpoint. See
and the section "My IPv4 endpoint address is dynamic".
