Windows 10 script to enable/disable TCP port

I want to simulate Oracle disconnect for my app. I need to enable/disable outgoing traffic to port 1521 quickly.

I think the best way is to add/remove a rule into the Windows Firewall.

Is there a CMD or PowerShell scrip I can use? Or WMI in C#?

(Note: I cannot disable networking as a whole because there are different connections are used in my code and only 1521 needs to be disabled).

Thanks for Anas Atef, I had to roll the sleeves up. Here is what one needs in the situation like mine:

New-NetFirewallRule -DisplayName "Disabling Port 1521" -Action Block -Direction Outbound -Profile Any -Protocol tcp -RemotePort 1521
Set-NetFirewallRule -DisplayName "Disabling Port 1521" -Action Allow
Set-NetFirewallRule -DisplayName "Disabling Port 1521" -Action Block
Remove-NetFirewallRule -Name "{751a86cb-2ef3-4eba-8c95-68aa7e4bde18}"

New creates the rule. The display name is whatever you like.

Set then helps you to enable/disable the rule effectively.

Then use Remove once you are done testing. The Name in the Remove command is the guid which you get after running New (watch the output).
