Without using anything external to Windows 2000, how can I set up a box so that
it will only respond and allow a single port (TCP and UDP) to pass on its NIC?
 
If you mean incoming connections, use TCP/IP filtering. TCP/IP
Properties/Advanced/Options tab.

you could lose alot of functionality if you block all ports except one
TCP and one UDP.

Doug - I'm mostly after blocking incoming connections. This box would only be
accessed on the network using Netop remote control (and I think it only needs a
single port)- and it would not be part of the domain or use any MS network
services.

I would also like to be able to block outgoing - in case it were to become
infected - would be nice to block its ability to talk to the outside world
(except exept in response to an incoming request on the singe port I'd open).

Thanks, Les Caudle
