Open Port Checker

Is a port on your own public IP reachable from the internet? Test port forwards and exposed RDP, SSH, camera or game ports, up to 10 at once.

Checks whether ports on your own public IP address can be reached from the internet: is the port forward for your game server, camera, VPN or web server working, or is Remote Desktop exposed when it shouldn't be? tclient.com's server tries a TCP connection to your address on each port and closes it again without sending anything. It can only test the address you're visiting from, never anyone else's. If you're on a VPN, that's the VPN's address.
