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

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::1 64
up
Reconfigure it:
sh /etc/netstart enc0
Enable IPv6 forwarding:
freedom# cat /etc/sysctl.conf
hw.smt=1
net.inet.ip.forwarding=1
net.inet6.ip6.forwarding=1
Same thing with sysctl (as root):
sysctl net.inet6.ip6.forwarding=1
