i have one computer that is connected to the internet through a dial up networking account and the reset of the LAN is connected to the internet through the winproxy program that is installed on the main computer

A proxy is often used as part of a firewall. The main idea is that the proxy machine is the only one that actually connects to the internet and hence the only one visible from the internet.

Each individual machine on the LAN will have an individual IP address, but all of them will appear to disappear into the proxy machine from the internet side and appear to emerge from the proxy machine on the LAN side.

Cheers,

Raymond.

I guess he would use the IP address of your machine. I don't know what the program server does so I can't tell :-(

I would get a hold of the person who sent it to you and get them to explain...

cheers,

Raymond
