Hello,
Does anybody here have a working IPv6 tunnel into an ec2 instance? I
seem to have trouble setting this up. The He.net configuration helper
suggests the following (which seems about right to me):
ifconfig gif0 create
ifconfig gif0 tunnel 50.16.84.149 216.66.38.58
ifconfig gif0 inet6 2001:470:1c:7e0::2 2001:470:1c:7e0::1 prefixlen 128
route -n add -inet6 default 2001:470:1c:7e0::1
But the EC2 instance (NetBSD 6.0_BETA, ami-37805e5e) does not seem to be
get any IPv6 connectivity:
# ifconfig -a
xennet0: flags=8863<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST> mtu 1500

I can see no IPv6 traffic at all.
The Amazon firewall is completely open, and a Linux instance works just
fine in the same security group.
Any ideas?
