For instance, if you're facing connection issues with a program (email, IM client etc) then it may be possible that the port required by the application is getting blocked by your router's firewall or your ISP. In such cases, this tool might help you in diagnosing any problem with firewall setup.

If you host and play games like Minecraft, use this checker to make sure the server port(25565) is configured properly for port forwarding, then only your friends will be able to connect to your server."

"If you're looking for a full list of port numbers check out this wikipedia page. I've listed all the common ports above, feel free to enter any custom port number to check. By default, this site is taking your device's IP address as target ip address (the device through which you're visiting this web page), but you can change the IP input field to check for other IP addresses - remote clients and servers as well. But, please don't misuse this option otherwise, I would have to restrict the IP address to source again (as I had done earlier). Please keep in mind that if you're using a VPN or proxy server then it may not be able to get your device's IP correctly."
