Control Connections to Virtual Servers
To enhance security, you can selectively include or exclude specific computers, subnets, and entire domains from accessing a virtual server. By default, all computers are allowed access to the server until you add them to a list of restricted computers. You can restrict access to a virtual server by either listing the computers that can access the server, or by specifying a group of computers that cannot.
