Firewall
PowerShell supports the NetSecurity module that contains cmdlets to manage local Network Security configurations such as Windows firewall rules and IP security settings.
To manage firewall settings, use cmdlets that have the text “NetFirewall” in their names. For firewall rule management, use cmdlets that contain the noun “NetFirewallRule.”
| Cmdlet | Description |
|---|---|
| New-NetFirewallRule | Creates a new firewall rule |
| Set-NetFirewallRule | Sets properties for a firewall rule |
| Get-NetFirewallRule | Gets properties for a firewall rule |
| Remove-NetFirewallRule | Deletes a firewall rule |
| Rename-NetFirewallRule | Renames a firewall rule |
| Copy-NetFirewallRule | Makes a copy of a firewall rule |
| Enable-NetFirewallRule | Enables a firewall rule |
| Disable-NetFirewallRule | Disables a firewall rule |
| Get-NetFirewallProfile | Gets properties for a firewall profile |
| Set-NetFirewallProfile | Sets properties for a firewall profile |
You can use the Get-NetFirewallRule cmdlet to retrieve settings for firewall rules. You can enable and disable rules by using one of the following cmdlets:
- The Set-NetFirewallRule cmdlet with the -Enabled parameter
- The Enable-NetFirewallRule or Disable-NetFirewallRule cmdlets.
The following commands both enable firewall rules in the group Remote Access:
Enable-NetFirewallRule -DisplayGroup "Remote Access"
## and
Set-NetFirewallRule -DisplayGroup "Remote Access" -Enabled True
