What is DynDNS?

If you are bored at work and some kind of security implementation is blocking your web browser from displaying facebook, myspace, ESPN360 and so on, what can you do? Well, that's no problem!!! If you are setup with DynDNS, you will be able to remote into your home computer and access all your files and softwares, and let's not forget you will be able to access any web page your home computer permits. Since most of the company/corporation have port 3389 enable for remote workers to access their files or computer from a different location, a remote connection shouldn't be impossible.

According to Wikipedia, Dynamic Network Services, Inc. (Dyn Inc.) is a network services company best-known for its free DynDNS dynamic DNS service, which allows users to have a subdomain that points to a computer with regularly-changing IP addresses, such as those served by many consumer-level Internet service providers. An update client installed on the user's computer, or built into a networked device such as a router or webcam, keeps the hostname up to date with its current IP address. Another popular free service provided by the company is internet content filtering. DynDNS also offers paid domain registrations, recursive DNS, e-mail forwarding and redirection, SSL certificates, network monitoring, URL redirection, and Virtual private server hosting. It has its corporate headquarters in Manchester, New Hampshire.

All it requires is, a free domain account from www.DynDNS.com, email access, DynDNS update client, port forwarding, firewall configuration, and windows' Remote Desktop Connection, and an internet connection. You wont need a static IP address as different ISPs claim. We will demonstrate how it is done. Besides, this is a free service.

  • note: Computer you are trying to remote into must be turned on.

  • Now, it is time to download the DynDNS client and install it. An update client is a computer application or a feature in your router that keeps your hostname's IP address up-to-date. The update client periodically checks your network's IP address; if it sees that your IP address has changed, it sends (updates) the new IP address to your hostname in your DynDNS.com account.

  • Once installed on the Host, login with the credential created earlier

  • Apply the settings, and status should be "Good", which means the IP address and domain name are synchronized.

Firewall Settings

  • Depending on your firewall, Remote Desktop will not work if it is blocked. I am using AVG Internet Security, which features a Firewall profile "Computer in Domain" and will allow remote desktop.
