💡 PowerShell Tip – Find a Windows Firewall rule by port

If you know the port but not the rule name, you can resolve the rule via the port filter:

Get-NetFirewallPortFilter | Where-Object { $_.LocalPort -eq 11434 } | Get-NetFirewallRule

Get-NetFirewallPortFilter | Where-Object { $_.LocalPort -eq 11434 } | Get-NetFirewallRule

Useful for troubleshooting when an application opens a port but the corresponding firewall rule name is unknown.
