I am trying to configure my public IPv6 machine, which is connected via a gif
tunnel to Hurricane Electric,  to route my public IPv6 addresses over my IPv4
VPN (which I can't natively deploy IPv6 on yet..).   What I would like to do,
is to take the subnet 2001:470:1f01:409:0:f00d:3:0/112 and route it from
10.24.5.10 (tlp1 on system #1) to 10.24.0.9 (ex0 on system #2), and to have
system #2's ex0 interface have the public IPv6 address
2001:470:1f01:409:0:f00d:3:1,  I am assuming I will have to use a seperate
(/128) subnet for IPv6 communications on the tunnel?

If anyone thinks they can help I'd be very greatful,  We're trying to get this
tunnel up and running!   Thanks
