Port check 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. It is the most useful tool when it comes to troubleshooting problems such as remote desktop, viewing DVR remotely and hosting websites on a dynamic IP. It is for remotely verifying if a port is open or closed. We receive lots of support tickets from our users saying that dynamic DNS service is not working for them since they cannot connect to a remote computer using the hostname signed up with us.
8 out 10 of those cases are due to port forwarding not being set up in their router.
If you are setting up dynamic DNS service to view your home security camera online remotely, or reach your web server hosted at home, or remote desktop into your
computers in remote locations and the hostname does not conenct.
The first thing you can do is open our Port Check
page, put in your IP address and the port the application is running on to check if the port is open or not.
Remote desktop port is 3389, DVR/Cam port is normally 80 or whichever port you have set up in your camera, and web server runs on port 80 by default.
In case you get a 'Fail' result, you can refer to our port forwarding tutorial to set it up in your router.
