Description

The Get-NetFirewallAddressFilter cmdlet returns address filter objects associated with the input rules.

Address filter objects represent the local and remote addresses associated with the input rules. The LocalAddress and RemoteAddress parameters of a single rule are represented in a separate NetFirewallAddressFilter object. The filter-to-rule relationship is always one-to-one and is managed automatically. Rule parameters associated with filters can only be queried using filter objects.

This cmdlet retrieves the addresses associated with firewall, IPsec, and IPsec main-mode rules. This allows for rule querying based on address fields using the LocalAddress or RemoteAddress parameters; this cmdlet returns filter objects that may be further queried with the Where-Object cmdlet. The resultant filters are passed to the Get-NetFirewallRule, Get-NetIPsecRule, or Get-NetIPsecMainModeRule cmdlet to return the rules queried by address.

To modify rule address conditions, two methods can be used starting with the address filters returned by this cmdlet and optional additional querying.

• The address filter objects can be piped into the Get-NetFirewallRule, Get-NetIPsecRule, or Get-NetIPsecMainModeRule cmdlet, which returns the rule objects associated with the filters. These rules are then piped into the Set-NetFirewallRule, Set-NetIPsecRule, or Set-NetIPsecMainModeRule cmdlet where the address properties can be configured.
• Alternatively, piping the address filter objects directly into the Set-NetFirewallAddressFilter cmdlet allows the LocalAddress and RemoteAddress parameters of the rules to be specified.

Examples

EXAMPLE 1

PS C:\>Get-NetIPsecRule -PolicyStore ActiveStore


This cmdlet shows the same information in a dynamically-sized, formatted table.
PS C:\>Get-NetIPsecRule -PolicyStore ActiveStore | Format-Table

This example retrieves the addresses associated with all the rules in the active store. Running this cmdlet without specifying the policy store retrieves the persistent store.

EXAMPLE 2

PS C:\>Get-NetFirewallRule -DisplayGroup "Core Networking" | Get-NetFirewallAddressFilter | Where-Object -FilterScript { $_.RemoteAddress -Eq "LocalSubnet6" }

This example gets the address configurations associated with a particular IPsec rule.

EXAMPLE 3

PS C:\>Get-NetFirewallRule -DisplayGroup "Core Networking" | Get-NetFirewallAddressFilter | Where-Object -FilterScript { $_.RemoteAddress -Eq "LocalSubnet6" } | Set-NetFirewallAddressFilter -RemoteAddress LocalSubnet4


This is an alternate method with this cmdlet.
PS C:\>Get-NetFirewallRule -DisplayGroup "Core Networking" | Get-NetFirewallAddressFilter | Where-Object -FilterScript { $_.RemoteAddress -Eq "LocalSubnet6" } | Get-NetFirewallRule | Set-NetFirewallRule -RemoteAddress LocalSubnet4

This example gets the filter objects associated with the firewall rules with a particular remote, second, endpoint belonging to the Core Networking group and modifies the second endpoint of those rules.

Inputs

CimInstance[]

The Microsoft.Management.Infrastructure.CimInstance object is a wrapper class that displays Windows Management Instrumentation (WMI) objects. The path after the pound sign (#) provides the namespace and class name for the underlying WMI object.
