  • Reference
Module:
NetNat

Adds a static mapping to a NAT instance.

Syntax

Add-NetNatStaticMapping
   [-NatName] <String>
   -Protocol <Protocol>
   [-RemoteExternalIPAddressPrefix <String>]
   -ExternalIPAddress <String>
   -ExternalPort <UInt16>
   -InternalIPAddress <String>
   [-InternalPort <UInt16>]
   [-InternalRoutingDomainId <String>]
   [-CimSession <CimSession[]>]
   [-ThrottleLimit <Int32>]
   [-AsJob]
   [-WhatIf]
   [-Confirm]
   [<CommonParameters>]

Description

The Add-NetNatStaticMapping cmdlet adds a static mapping to a network address translation (NAT) instance. A static mapping enables an incoming connection from an external network to access a host on an internal network through the NAT.

You can use NAT to share a connection to the public Internet through a single interface with a single public IP address. The computers on the private network use private, non-routable addresses. NAT maps the private addresses to the public address.

Examples

Example 1: Add a static mapping to a NAT instance

PS C:\> Add-NetNatStaticMapping -ExternalIPAddress "a.b.c.0/24" -ExternalPort 80 -InternalIPAddress "192.0.02.179" -InternalPort 8080 -InternalRoutingDomainId "{12345678-0000-0000-0000-123456789012}"

This command adds a static mapping to a NAT instance. The command specifies that NAT maps the external IP address to the internal IP address 192.0.02.179. The command specifies that the NAT maps the destination port 80 of the Internet resource to the source application port 8080. The command specifies that the tenant compartment that has the ID TSQATenant contains the internal address and internal port. This example uses the placeholder a.b.c.0/24 to represent a public Internet address prefix.

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
Required:False
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
Required:False
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
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-ExternalIPAddress

Specifies the external IP address to which an incoming connection is addressed. This parameter specifies the destination IP address in the incoming packet.

Type:String
Position:Named
Default value:None
Required:True
Accept pipeline input:False
Accept wildcard characters:False

-ExternalPort

Specifies the external port to which an incoming connection is sent. This parameter specifies the destination port in the incoming TCP or UDP packets.

Type:UInt16
Position:Named
Default value:None
Required:True
Accept pipeline input:False
Accept wildcard characters:False

-InternalIPAddress

Specifies the IP address to which the packets from a remote machine in the external network are addressed.

Type:String
Position:Named
Default value:None
Required:True
Accept pipeline input:False
Accept wildcard characters:False

-InternalPort

Specifies the internal port to which the packets from a remote machine in the external network are sent. If you do not specify this parameter, NAT uses the port that you specify for the ExternalPort parameter for the internal port.

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

-InternalRoutingDomainId

Specifies the GUID of the routing domain of the internal interface.

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

-NatName

Specifies the name of the NAT instance.

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

-Protocol

Specifies the network protocol of the client computer in the internal network. The acceptable values for this parameter are:

  • TCP
  • UDP
Type:Protocol
Accepted values:TCP, UDP
Position:Named
Default value:None
Required:True
Accept pipeline input:False
Accept wildcard characters:False

-RemoteExternalIPAddressPrefix

Specifies the IP address prefix of the remote computer on the external network.

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