Introduction
We will create an IPv6 tunnel (provided by Hurricane Electric suitable for subnetting (/48).
Configuration
In /etc/hostname.gif0:
tunnel 207.246.122.61 209.51.161.14 !ifconfig gif0 inet6 alias 2001:470:1f06:95f::2 2001:470:1f06:95f::1 prefixlen 128 !route -n add -inet6 default 2001:470:1f06:95f::1
Enable it (as root):
sh /etc/netstart gif0
Test
Check that it works:

Routing
Assign IPs to the interface you wish to route to:
freedom# cat /etc/hostname.enc0 inet 172.24.24.1 255.255.255.0 172.24.24.255 inet6 2001:470:8c78:a0:: 64 up
