This window is accessed via the Security Tab on the Virtual Server Properties window. Based on the settings of the Access Control window, connections will either be allowed to continue or terminated. In the event that an IP Address is matched on both the Allowed Access and Denied Access tabs, the connection will be denied for security purposes. The only exception to this is if an IP address matches a network range on the Denied Access tab, and is a Single Computer match on the Allowed Access tab.
There are two tabs available on this window, the Allowed Access tab and the Denied Access tab. These tabs both contain an Add… button which is described on this page for convenience.
