Description: A free open port check tool used to detect open ports on your connection. Test if port forwarding is correctly setup or if your port is being blocked by your firewall or ISP.
This is a free utility for remotely verifying if a port is open or closed. It is useful to users who wish to verify port forwarding and check to see if a server is running or a firewall or ISP is blocking certain ports.
Port forwarding or port mapping allows remote computers to connect to a specific computer or service on a private network. This allows you to run a web server, game server or a service of your choosing from behind a router.
In a typical network the router has the public IP address and computers/servers obtain a private IP address from the router that is not addressable from outside the network. When you forward a specific port on your router, you are telling your router where to direct traffic for that port. This utility can verify the success of that process.
