As such, Port 22 is subject to countless, unauthorized login attempts by hackers who are attempting to access unsecured servers. A highly effective deterrent is to simply turn off Port 22 and run the service on a seemingly random port above 1024 (and up to 65535).

Is it OK to leave ports open?

Open ports aren't dangerous by default, rather it's what you do with the open ports at a system level, and what services and apps are exposed on those ports, that should prompt people to label them dangerous or not. The reason people call for closed ports because less open ports reduces your attack surface.

Check the Enabled option, give the forwarding rule a name, specify the local static IP address you've set previously, and enter the Minecraft server port. In this case, it's 25565. Don't forget to apply the configuration for both TCP and UDP ports. Once done, save the changes.

How do you check if a port is blocked?

Enter "telnet + IP address or hostname + port number" (e.g., telnet www.example.com 1723 or telnet 10.17.xxx.xxx 5000) to run the telnet command in Command Prompt and test the TCP port status. If the port is open, only a cursor will show. If the port is closed, a message will say Connect failed.
