Yes I've got a 10.04 server with an IPv4 fixed address like so:-

iface eth0 inet static
  network   192 168.2.0

reached from outside via NAT and port forwarding configured on my

Will the IPv6 address simply be added to the above
in /etc/network/interfaces? Obviously the router will also need to be
worked on. I have the Cisco/Linksys WRT160NL which I think I can flash
