This is just like the old pre-configured sunos IP numbers. That was part of the reason for RFC1597 anyway. Here's what I do: use another RFC1918 net for demonstration (try a class A number so it looks different) and pretend its routed. It doesn't (shouldn't) matter to the NAT. If you aren't connected to the net, it doesn't matter anyway. If you are connected to the net, then use the actual assigned network number, and have a real demonstration. --Dean ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Plain Aviation, Inc [email protected] LAN/WAN/UNIX/NT/TCPIP http://www.av8.com ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
