Specifies that matching firewall rules of the indicated action are retrieved.

This parameter specifies the action to take on traffic that matches this rule. The acceptable values for this parameter are:� Allow or Block.

-- Allow: Network packets that match all of the criteria specified in this rule are permitted through the firewall. This is the default value.

-- Block: Network packets that match all of the criteria specified in this rule are dropped by the firewall.

The default value is Allow. Note: The OverrideBlockRules field changes an allow rule into an allow bypass rule.

Indicates that all of the firewall rules within the specified policy store are retrieved.

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.

Gets the firewall rules that are associated with the given address filter to be retrieved.

A NetFirewallAddressFilter object represents the address conditions associated with a rule. See the Get-NetFirewallAddressFilter cmdlet

Gets the firewall rules that are associated with the given application filter to be retrieved.

A NetFirewallApplicationFilter object represents the applications associated with a rule. See the Get-NetFirewallApplicationFilter cmdlet

Gets the firewall rules that are associated with the given interface filter to be retrieved.

A NetFirewallInterfaceFilter object represents the interface conditions associated with a rule. See the Get-NetFirewallInterfaceFilter cmdlet

Gets the firewall rules that are associated with the given interface type filter to be retrieved.

A NetFirewallInterfaceTypeFilter object represents the interface conditions associated with a rule. See the Get-NetFirewallInterfaceTypeFilter cmdlet

Gets the firewall rules that are associated with the given port filter to be retrieved.

A NetFirewallPortFilter object represents the port conditions associated with a rule. See the Get-NetFirewallPortFilter cmdlet

Gets the firewall rules that are associated with the given firewall profile type to be retrieved.

A NetFirewallProfile object represents the profile conditions associated with a rule. See the Get-NetFirewallProfile cmdlet

Gets the firewall rules that are associated with the given security filter to be retrieved.

A NetFirewallSecurityFilter object represents the security conditions associated with a rule. See the Get-NetFirewallSecurityFilter cmdlet

Gets the firewall rules that are associated with the given service filter to be retrieved.

A NetFirewallServiceFilter object represents the profile conditions associated with a rule. See the Get-NetFirewallServiceFilter cmdlet

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.

Specifies that matching firewall rules of the indicated description are retrieved. Wildcard characters are accepted.

This parameter provides information about the firewall rule. This parameter specifies the localized, user-facing description of the IPsec rule.

Specifies that matching firewall rules of the indicated direction are retrieved.

This parameter specifies which direction of traffic to match with this rule. The acceptable values for this parameter are:� Inbound or Outbound.

The default value is Inbound.

Specifies that only matching firewall rules of the indicated group association are retrieved. Wildcard characters are accepted.

The Group parameter specifies the source string for this parameter. If the value for this parameter is a localizable string, then the Group parameter contains an indirect string. Rule groups can be used to organize rules by influence and allows batch rule modifications. Using the Set-NetFirewallRule cmdlet, if the group name is specified for a set of rules or sets, then all of the rules or sets in that group receive the same set of modifications. It is good practice to specify the Group parameter value with a universal and world-ready indirect @FirewallAPI name. Note: This parameter cannot be specified upon object creation using the New-NetFirewallRule cmdlet, but can be modified using dot-notation and the Set-NetFirewallRule cmdlet.

Specifies that only matching firewall rules of the indicated display name are retrieved. Wildcard characters are accepted.

Specifies the localized, user-facing name of the firewall rule being retrieved. When creating a rule this parameter is required. This parameter value is locale-dependent. If the object is not modified, this parameter value may change in certain circumstances. When writing scripts in multi-lingual environments, the Name parameter should be used instead, where the default value is a randomly assigned value. Note: This parameter cannot be set to All.

Specifies that matching firewall rules of the indicated edge traversal policy are retrieved.

This parameter specifies how this firewall rule will handle edge traversal cases. Edge traversal allows the computer to accept unsolicited inbound packets that have passed through an edge device, such as a network address translation (NAT) router or firewall. This option applies to inbound rules only. The acceptable values for this parameter are:� Block, Allow, DeferToUser, or DeferToApp.

-- Block: Prevents applications from receiving unsolicited traffic from the Internet through a NAT edge device.

-- Allow: Allows applications to receive unsolicited traffic directly from the Internet through a NAT edge device.

-- DeferToUser: Allows the user to decide whether to allow unsolicited traffic from the Internet through a NAT edge device when an application requests it.

-- DeferToApp: Allows each application to determine whether to allow unsolicited traffic from the Internet through a NAT edge device.

The default value is Block. Note: The DeferToApp and DeferToUser options are only valid for computers running Windowsr7, WindowsServerr2008R2, and Windows Serverr 2012.

Specifies that matching firewall rules of the indicated state are retrieved.

This parameter specifies that the rule object is administratively enabled or administratively disabled. The acceptable values for this parameter are:

-- True: Specifies the rule is currently enabled.

-- False: Specifies the rule is currently disabled. A disabled rule will not actively modify computer behavior, but the management construct still exists on the computer so it can be re-enabled.

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 PowerShellr, 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 the domain GPO 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.

Specifies that only matching firewall rules of the indicated group association are retrieved. Wildcard characters are accepted.

This parameter specifies the source string for the DisplayGroup parameter. If the DisplayGroup parameter value is a localizable string, then this parameter contains an indirect string. Rule groups can be used to organize rules by influence and allows batch rule modifications. Using the Set-NetFirewallRule cmdlet, if the group name is specified for a set of rules or sets, then all of the rules or sets in that group receive the same set of modifications. It is a good practice to specify this parameter value with a universal and world-ready indirect @FirewallAPI name. Note: The DisplayGroup parameter cannot be specified upon object creation using the New-NetFirewallRule cmdlet, but can be modified using dot-notation and the Set-NetFirewallRule cmdlet.

Indicates that matching firewall rules of the indicated value are retrieved.

This parameter specifies the firewall rules for local only mapping, which describes whether a packet must pass through a local address on the way to the destination.

Non-TCP traffic is session-less. Windows Firewall authorizes traffic per session, not per packet, for performance reasons. Generally, non-TCP sessions are inferred by checking the following fields: local address, remote address, protocol, local port, and remote port.

If this parameter is set to True, then the remote address and port will be ignored when inferring remote sessions. Sessions will be grouped based on local address, protocol, and local port.

This is similar to the LooseSourceMapping parameter, but performs better in cases where the traffic does not need to be filtered by remote address. This could improve performance on heavy server workloads where UDP requests come from dynamic client ports. For instance, Teredo relay servers.

Indicates that matching firewall rules of the indicated value are retrieved.

This parameter specifies the firewall rules for loose source mapping, which describes whether a packet can have a non-local source address when being forwarded to a destination.

If this parameter is set to True, then the rule accepts packets incoming from a host other than the one to which the packets were sent. This parameter applies only to UDP protocol traffic.

The default value is False.

Specifies that only matching firewall rules of the indicated name are retrieved. Wildcard characters are accepted.

This parameter acts just like a filename, in that only one rule with a given name may exist in a policy store at a time. During group policy processing and policy merge, rules that have the same name but come from multiple stores being merged, will overwrite one another so that only one exists. This overwriting behavior is desirable if the rules serve the same purpose. For instance, all of the firewall rules have specific names, so if an administrator can copy these rules to a GPO, and the rules will override the local versions on a local computer. GPOs can have precedence. So if an administrator has a different or more specific rule with the same name in a higher-precedence GPO, then it overrides other rules that exist.

The default value is a randomly assigned value.

When the defaults for main mode encryption need to overridden, specify the customized parameters and set this parameter, making it the new default setting for encryption.

Specifies that matching firewall rules of the indicated owner are retrieved.

This parameter specifies the owner of the firewall rule, represented as an SDDL string. All Windows Store applications that require network traffic create network isolation rules (normally through installing via the Store), where the user that installed the application is the owner. This parameter specifies that only network packets that are authenticated as coming from or going to an owner identified in the list of accounts (SID) match this rule.

Targets 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_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 added for third-party services. In addition, network isolation rules that are created for Windows Store application containers will appear in this policy store.

The default value is PersistentStore. Note: The Set-NetFirewallRule cmdlet cannot be used to add an object to a policy store. An object can only be added to a policy store at creation time with the Copy-NetFirewallRule or with the New-NetFirewallRule cmdlet.

Specifies that firewall rules matching the indicated policy store source are retrieved.

This parameter contains a path to the policy store where the rule originated if the object is retrieved from the ActiveStore with the TracePolicyStoreSource option set. This parameter value is automatically generated and should not be modified.

The monitoring output from this parameter is not completely compatible with the PolicyStore parameter. This parameter value cannot always be passed into the PolicyStore parameter. Domain GPOs are one example in which this parameter contains only the GPO name, not the domain name.

Specifies that firewall rules that match the indicated policy store source type are retrieved.

This parameter describes the type of policy store where the rule originated if the object is retrieved from the ActiveStore with the TracePolicyStoreSource option set. This parameter value is automatically generated and should not be modified. The acceptable values for this parameter are:�

-- Local: The object originates from the local store.

-- GroupPolicy: The object originates from a GPO.

-- Dynamic: The object originates from the local runtime state. This policy store name is not valid for use in the cmdlets, but may appear when monitoring active policy.

-- Generated: The object was generated automatically. This policy store name is not valid for use in the cmdlets, but may appear when monitoring active policy.

-- Hardcoded: The object was hard-coded. This policy store name is not valid for use in the cmdlets, but may appear when monitoring active policy.

Specifies that firewall rules that match the indicated primary status are retrieved.

This parameter specifies the overall status of the rule.

-- OK: Specifies that the rule will work as specified.

-- Degraded: Specifies that one or more parts of the rule will not be enforced.

-- Error: Specifies that the computer is unable to use the rule at all.

Specifies that firewall rules that match the indicated status are retrieved.

This parameter describes the status message for the specified status code value. The status code is a numerical value that indicates any syntax, parsing, or runtime errors in the rule or set. This parameter value should not be modified.

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 PowerShellr 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.

Specifies that the name of the source GPO is queried and set to the PolicyStoreSource parameter value.

This cmdlet supports the common parameters: Verbose, Debug,ErrorAction, ErrorVariable, WarningAction, WarningVariable,OutBuffer, PipelineVariable, and OutVariable.
