PFPortChecker  

PFPortChecker is a tool provided by Portforward.com that allows you to check if the ports on your network are correctly open and accessible.

Checking your ports ensures that devices or services requiring open ports, such as online gaming, file sharing, or remote access, can function properly.

PFPortChecker tests individual ports on your network by attempting to establish a connection to them. It then determines if the connection was successful or not.

Yes, PFPortChecker is completely free for users to check the status of their ports.

Yes, PFPortChecker is compatible with Windows, macOS, and Linux operating systems.

If a port is open, it means that the specified device or service using that port can accept incoming connections from the internet.

If a port is closed, it means that the specified device or service using that port is not currently accepting incoming connections from the internet.

If a port is blocked, it means that there is some form of firewall or network restriction preventing incoming connections on that port.

To open a closed or blocked port, you may need to configure your router's port forwarding settings or adjust your firewall rules accordingly.

PFPortChecker itself cannot fix port forwarding issues, but it helps diagnose whether your ports are accessible. You may need to manually configure your router settings to resolve any issues.
