Description

The Add-NetNatExternalAddress cmdlet adds an external address to a network address translation (NAT) instance.

Examples

Example 1: Add an external address

PS C:\> Add-NetNatExternalAddress -IPAddress "a.b.c.0/24"

This command adds the external address 10.20.30.120 to a NAT. This example uses the placeholder a.b.c.0/24 to represent a public Internet address prefix.

Example 2: Add an external address and a port range

PS C:\> Add-NetNatExternalAddress -IPAddress "a.b.c.0/24" -PortEnd 19999 -PortStart 10000

This command adds an external address to a specified NAT, and specifies a range of ports to use for outbound connections. This example uses the placeholder a.b.c.0/24 to represent a public Internet address prefix.

Required Parameters

-IPAddress

Specifies an external IP address for a NAT, as a string.

Type:String
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-NatName

Specifies the name for the NAT instance, as a string.

Type:String
Position:0
Default value:None
Accept pipeline input:False
Accept wildcard characters:False

Optional Parameters

-AsJob

Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete.

The cmdlet immediately returns an object that represents the job and then displays the command prompt. You can continue to work in the session while the job completes. To manage the job, use the *-Job cmdlets. To get the job results, use the Receive-Job cmdlet.

For more information about Windows PowerShell background jobs, see about_Jobs.

Type:SwitchParameter
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-CimSession

Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSession or Get-CimSession cmdlet. The default is the current session on the local computer.

Type:CimSession[]
Aliases:Session
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-Confirm

Prompts you for confirmation before running the cmdlet.

Type:SwitchParameter
Aliases:cf
Position:Named
Default value:False
Accept pipeline input:False
Accept wildcard characters:False
-PortEnd

Specifies the high end of a dynamic port range from which to pick a port for a NAT session. Choose a port number that is greater than the PortStart parameter from the available ports. NAT associates a port number with an external address to identify the mapping between an internal network and an external network.

Type:UInt16
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-PortStart

Specifies the low end of a dynamic port range from which to pick a port for a NAT session. Choose a port number that is less than the PortEnd parameter from the available ports. NAT associates a port number with an external address to identify the mapping between an internal network and an external network.

Type:UInt16
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-ThrottleLimit

Specifies the maximum number of concurrent operations that can be established to run the cmdlet. If this parameter is omitted or a value of 0 is entered, then Windows PowerShell® calculates an optimum throttle limit for the cmdlet based on the number of CIM cmdlets that are running on the computer. The throttle limit applies only to the current cmdlet, not to the session or to the computer.

Type:Int32
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-WhatIf

Shows what would happen if the cmdlet runs. The cmdlet is not run.

Type:SwitchParameter
Aliases:wi
Position:Named
Default value:False
Accept pipeline input:False
Accept wildcard characters:False
