Configure IPv4 Address Restrictions for Remote Connections (IIS 7)
Applies To: Windows Server 2008, Windows Server 2008 R2
Configure IPv4 address restrictions to specify whether a specific IPv4 address or range of IPv4 addresses are allowed or denied permission to connect remotely to sites or applications on the Web server. For example, if the management service is experiencing a denial-of-service (DOS) attack or an unauthorized attempt to access the service, you can deny remote connections from the specific IP addresses from where the attacks originate.
Only server administrators who are using IIS Manager on the local computer can configure the management service in IIS 7.
For information about the levels at which you can perform this procedure, and the modules, handlers, and permissions that are required for this procedure, see Management Service Feature Requirements (IIS 7).
