Thank you so much for your help! I removed the dhcp segment 10.xxxx. I don’t know how to change the win proxy transparent mode. Our windows network was setup by some university guys paid by the Feds under a grant. They left and now we teachers have to support it.
So, I will research how to create transparent proxy in windows.
Fulvio, words escape me on how to tell you how much I appreciate your help.
thanks
