Netsh commands for routing IP NAT

The following entries provide details for each command.

dump

Displays the Network Address Translation (NAT) configuration of a remote access server in script form.

Syntax

dump

Remarks

  • You can dump the contents of the current configuration to a file that can be used to restore altered configuration settings.

Example

The following commands save the current configuration as a script in the c:\test\natcfg.dmp file.

  • From the command prompt:

    netsh routing ip nat dump > c:\test\natcfg.dmp

  • From the netsh routing ip nat context prompt:

    set file open c:\test\natcfg.dmp

    dump

    set file close

You can use the netsh exec command to run the script created by the netsh dump command.
