I have previously written several articles on the remote desktop, which include how to enable the remote desktop on a remote computer and how to access local files and folders during a remote desktop session. I have even written about how to block remote connections to a PC!
However, I have not talked about how to really configure a router for the remote desktop so that it can connect to your computer from outside the local network. Once you enable and configure the remote desktop, you must configure your router to forward the remote desktop port (3389 by default) to the correct computer on your network.
This is called port forwarding and the method is slightly different depending on the router of the brand you are using, that is, LinkSys, D-Link, Netgear, etc. However, if the instructions below do not help you determine how to configure port forwarding on your router, then simply search for a "router port router", where the router is the router's mark.
Configure router for remote desktop
First, you must log in to your wireless router at home by typing the local IP address for the router in your Internet browser. If you don't know the router's IP address, go to Start, Run and type CMD. Then write IPCONFIG and the router address is the entry of the Default Gateway .
Now type that IP address in your browser and log in to your router. If you don't know the username and administrator password of your router, you can reset the router by pressing the reset button on the back and then go to any of these sites in the router's default password list:
Once on the router, look for anything on the line of Port Forwarding, Virtual Server or Applications and games. Try to find a couple of screenshots of how it will look on LinkSys, D-link and Netgear:
Now you can choose the service of some type of drop-down menu that will have a list such as FTP, HTTP, TELNET, etc. And if they have Remote Desktop or RDP, then choose that option. Enter the IP address in the corresponding box and you're done.
If the service is not listed, you must add a personalized service or there will be some blank boxes where you can enter the information. On my Linksys router, for example, I have a lot of empty text boxes in a table.
I would like to access Remote Desktop for the name of the application, 3389 for the internal port, 3389 For the external port, choose both TCP as UDP as the protocol, write the IP address of the computer to which I want to connect and check the box enabled.
In a D-link router, it is called Port private and port public in instead of internal and external ports, but it is always the same number 3389, so it cannot be confused. In Netgear, it is called the port of start and port of completion .
Now everything must be configured to connect to your computer from outside the local network. To connect from the outside, you will have to obtain your external IP address, which is simple. Simply go to www.whatismyip.com and give it your external IP address.
The only problem that may arise is if you do not have a static IP address with your ISP. Most home users get a dynamic IP address that changes from time to time. This makes it extremely difficult to connect remotely because it fails once the IP address changes.
To solve this problem, you can read my detailed article in Online Tech Tips that talks about how to configure dynamic DNS for remote desktop on your PC. Any questions? Post a comment! Enjoy!
