Port Check Tool
Port Check Tool is a site owned and operated by No-IP. The site allows you to view your current public IP address. It also gives you the ability to run a test on the port number(s) you have forwarded within your router.
This information can be used for troubleshooting port forwarding issues or configuring remote access. You can also test whether specific router ports have been forwarded correctly.
