Description

The Set-NetNat cmdlet modifies settings for Network Address Translation (NAT) objects. NAT modifies IP address and port information in packet headers. Use this cmdlet to modify the following:

• Time-out values for ICMP and UDP sessions and TCP connections.
• Behavior of TCP and UDP filtering.
• Whether packets from external networks refresh UDP sessions.

Specify NAT objects to modify by using the Name parameter or by using the Get-NetNat cmdlet. Use the New-NetNat cmdlet to create NAT objects.

Examples

Example 1: Modify settings for a NAT object

PS C:\> Set-NetNat -Name "TSQATenant" -TcpFilteringBehavior AddressDependentFiltering -UdpInboundRefresh $True

This command modifies a NAT object named TSQATenant. The command specifies a value of $True for the UdpInboundRefresh parameter, and, therefore, NAT refreshes UDP sessions for both inbound and outbound packets. The command changes TCP filtering behavior to address dependent filtering.

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

-IcmpQueryTimeout

Specifies the length of the time-out period, in seconds, for an ICMP query session.

Type:	UInt32
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-InputObject

Specifies the input to this cmdlet. You can use this parameter, or you can pipe the input to this cmdlet.

Type:	CimInstance[]
Position:	Named
Default value:	None
Required:	True
Accept pipeline input:	True
Accept wildcard characters:	False

-Name

Specifies an array of names of NAT objects.

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

-PassThru

Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.

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

-TcpEstablishedConnectionTimeout

Specifies the length of the time-out period, in seconds, for established TCP connections. Use the TcpTransientConnectionTimeout parameter to modify the time-out period for transient TCP connections.

Type:	UInt32
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-TcpFilteringBehavior

Specifies filtering behavior for TCP connections. The acceptable values for this parameter are:

• EndpointIndependentFiltering
• AddressDependentFiltering

The default value is EndpointIndependentFiltering.

Type:	FilteringBehaviorType
Accepted values:	EndpointIndependentFiltering, AddressDependentFiltering
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-TcpTransientConnectionTimeout

Specifies the length of the time-out period, in seconds, for transient TCP connections. Use the TcpEstablishedConnectionTimeout parameter to modify the time-out period for established TCP connections.

Type:	UInt32
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

-UdpFilteringBehavior

Specifies filtering behavior for UDP sessions. The acceptable values for this parameter are:

• EndpointIndependentFiltering
• AddressDependentFiltering

The default value is EndpointIndependentFiltering.

Type:	FilteringBehaviorType
Accepted values:	EndpointIndependentFiltering, AddressDependentFiltering
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-UdpIdleSessionTimeout

Specifies the length of the time-out period, in seconds, for a UDP session.

Type:	UInt32
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-UdpInboundRefresh

Indicates whether a packet from the external network refreshes an existing UDP session. If you specify a value of $True for this parameter, either an inbound packet or an outbound packet refreshes an existing UDP session. If you specify a value of $False, only an outbound packet refreshes a UDP session. The default value is $False.

Type:	Boolean
Accepted values:	False, True
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
