Microsoft NetSecurity reference: Retrieves port filter objects from the target computer. The syntax and selected example below are adapted from the pinned Windows Server 2025 reference. Module availability, target configuration and delegated permissions determine whether it can run in your environment. Documentation and parameter text: Microsoft, CC BY 4.0; formatting adapted by Cmdlet World. No execution testing is claimed.
Use an account with the target resource permissions documented for Get-NetFirewallPortFilter. Modifying administrative cmdlets may require elevation or delegated administration. This catalog does not assert that ordinary users can execute the command.

Parameters
-All
Indicates that all of the port filters within the specified policy store are retrieved.
-AsJob
Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete.
-AssociatedNetFirewallRule (required)
Gets the port filter object associated with the specified firewall rule to be retrieved. This parameter represents a firewall rule, which defines how traffic is filtered by the firewall. See the New-NetFirewallRule cmdlet for more information.
-AssociatedNetIPsecRule (required)
Gets the phase 1 authentication sets that are associated, via the pipeline, with the input IPsec rule to be retrieved. A NetIPsecRule object represents an IPsec rule, which determines IPsec behavior. An IPsec rule can be associated with Phase1AuthSet, Phase2AuthSet, and NetIPsecQuickMode cryptographic sets. See the New-NetIPsecMainModeRule cmdlet for more information.
-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.
-DynamicTarget
Specifies an array of dynamic transports. The cmdlet returns port filter objects associated with the input rules that have the dynamic transports that you specify. The acceptable values for this parameter are: - Any - ProximityApps - ProximitySharing - WifiDirectPrinting - WifiDirectDisplay - WifiDirectDevices Some types of dynamic transports, such as proximity sharing, abstract the network layer details, and you cannot use standard network layer conditions, such as protocols and ports, to identify the dynamic transports.
-GPOSession
Specifies the network GPO from which to retrieve the rules to be retrieved. This parameter is used in the same way as the *PolicyStore* parameter. When modifying GPOs in Windows PowerShell®, each change to a GPO requires the entire GPO to be loaded, modified, and saved back. On a busy Domain Controller (DC), this can be a slow and resource-heavy operation. A GPO Session loads a domain GPO onto the local computer and makes all changes in a batch, before saving it back. This reduces the load on the DC and speeds up the Windows PowerShell cmdlets. To load a GPO Session, use the Open-NetGPO cmdlet. To save a GPO Session, use the Save-NetGPO cmdlet.
-PolicyStore
Specifies the policy store from which to retrieve the rules to be retrieved. A policy store is a container for firewall and IPsec policy. The acceptable values for this parameter are: - PersistentStore: Sometimes called static rules, this store contains the persistent policy for the local computer. This policy is not from GPOs, and has been created manually or programmatically (during application installation) on the computer. Rules created in this store are attached to the ActiveStore and activated on the computer immediately. - ActiveStore: This store contains the currently active policy, which is the sum of all policy stores that apply to the computer. This is the resultant set of policy (RSOP) for the local computer (the sum of all GPOs that apply to the computer), and the local stores (the PersistentStore, the static Windows service hardening (WSH), and the configurable WSH). ---- GPOs are also policy stores. Computer GPOs can be specified as follows. ------ -PolicyStore hostname. ---- Active Directory GPOs can be specified as follows. ------ -PolicyStore domain.fqdn.com\GPO_Friendly_Namedomain.fqdn.comGPO_Friendly_Name. ------ Such as the following. -------- -PolicyStore localhost -------- -PolicyStore corp.contoso.com\FirewallPolicy ---- Active Directory GPOs can be created using the New-GPO cmdlet or the Group Policy Management Console. - RSOP: This read-only store contains the sum of all GPOs applied to the local computer. - SystemDefaults: This read-only store contains the default state of firewall rules that ship with Windows Server® 2012. - StaticServiceStore: This read-only store contains all the service restrictions that ship with Windows Server 2012. Optional and product-dependent features are considered part of Windows Server 2012 for the purposes of WFAS. - ConfigurableServiceStore: This read-write store contains all the service restrictions that are
-Protocol
Specifies that network packets with matching IP addresses match this rule. This parameter specifies the protocol for an IPsec rule. The acceptable values for this parameter are: - Protocols by number: 0 through 255. - Protocols by name: TCP, UDP, ICMPv4, or ICMPv6. If a port number is identified by using port1 or port2, then this parameter must be set to TCP or UDP. The values ICMPv4 and ICMPv6 create a rule that exempts ICMP network traffic from the IPsec requirements of another rule. The default value is Any. Querying for rules with this parameter can only be performed using filter objects.
-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.
Prerequisites
Windows with the NetSecurity module and the Windows feature or management tools that provide it. Confirm target connectivity and version compatibility using the linked Microsoft reference.
Security considerations
This is a read-oriented cmdlet; protect any sensitive results and check the documented effects of your selected parameters.
This example retrieves the port conditions associated with all the rules in the active store. Running this cmdlet without specifying the policy store retrieves the persistent store. Source: Microsoft, CC BY 4.0; transcript prompt/output removed. This example was not executed.
