Port Check Tool: Test Your Port Forwarding Online

What is the No‑IP 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.

Tool ​​Summary

• Visit the Port Check Tool website to automatically detect your current public IP.
• Enter the port number you forwarded on your router to test if the port is open or blocked.
• Use the tool to verify that your router’s port forwarding setup is working properly.
• If the port appears closed, inspect router firewall rules, ISP port‑blocks, or device listening on that port.
• It’s a free online utility and works without installing software, just via your web browser.
