Hi,

I have windows 2000 adv. server with 15 windows 2000 prof. clients and i am using NAT for internet.I also installed IIS server and published some sites on my IIS server.My clients can access internet.Now i want the public users can access my IIS server as well as my private users can also access my IIS server.I am using Dialup connection so that’s y i don’t hv any public or static IP.
