How to Enable a Port Through PowerShell
Enabling a port through PowerShell is useful for network configurations, troubleshooting, or setting up applications that require specific ports. You can achieve this using the Windows Firewall cmdlets in PowerShell.
Steps to Enable a Port Using PowerShell
- Open PowerShell as Administrator
PressWin + Xand select Windows PowerShell (Admin). - Allow Incoming Traffic on a Specific Port
Run the following command to enable a port (e.g., TCP port 8080):
New-NetFirewallRule -DisplayName "Allow Port 8080" -Direction Inbound -Action Allow -Protocol TCP -LocalPort 8080 - Allow Outgoing Traffic on a Specific Port
If your application also needs to send data, enable outbound traffic:
New-NetFirewallRule -DisplayName "Allow Outbound Port 8080" -Direction Outbound -Action Allow -Protocol TCP -LocalPort 8080 - Verify the Firewall Rule
Check if the rule was added successfully:
Get-NetFirewallRule -DisplayName "Allow Port 8080" - Remove a Firewall Rule (If Needed)
If you need to delete the rule:
Remove-NetFirewallRule -DisplayName "Allow Port 8080"
