Netsh commands for Interface Portproxy

  • Article

Applies To: Windows Server 2008

The Netsh Interface Portproxy commands provide a command-line tool for use in administering servers that act as proxies between IPv4 and IPv6 networks and applications. You can use these commands to establish proxy service in the following ways:

  • IPv4-configured computer and application messages sent to other IPv4-configured computers and applications.

  • IPv4-configured computer and application messages sent to IPv6-configured computers and applications.

  • IPv6-configured computer and application messages sent to IPv4-configured computers and applications.

  • IPv6-configured computer and application messages sent to other IPv6-configured computers and applications.

When writing batch files or scripts using these commands, each command must be preceded by netsh interface portproxy. For example, when using the delete v4tov6 command to specify that the portproxy server delete an IPv4 port and address from the list of IPv4 addresses for which the server listens, the batch file or script must use the following syntax:

netsh interface portproxy delete v4tov6 listenport= {Integer | ServiceName} [[listenaddress=] {IPv4Address| HostName}] [[protocol=]tcp]

You can run these commands at the command prompt in a Windows Server®2008 operating system or at the command prompt for the netsh interface portproxy context. For these commands to work at the command prompt in Windows Server 2008, you must type netsh interface portproxy before typing commands and parameters as they appear in the syntax below.

add v4tov4

Specifies that the portproxy server listen for messages sent to a specific port and IPv4 address, and maps a port and IPv4 address to which to send the messages received after establishing a separate TCP connection.

Parameters

  • listenport
    Required. Specifies the IPv4 port, by port number or service name, on which to listen.
