There are only a few simple steps to configure port forwarding on Windows VPS. The command-line solution works just as well but it’s much more work.Īlso Read : List of the 6 Best Firewalls for Windows There are different ways to configure port forwarding on Windows VPS, but we will only discuss the simple, GUI solution. You also need to let clients connect to your web server. If you have a Windows VPS, port forwarding will be even more important, because you will definitely need to set up an SSH connection. How to Configure Port Forwarding on Windows VPS? With the stage set and the stakes properly introduced, we now get to do some actual port forwarding. It took me a while to figure it out and that can be very damaging if you’re running a business. There are other threats as well: once I had made the mistake of assigning two different apps to the same port, and of course, none of them worked anymore. If you don’t configure your firewall correctly, it can cut off important services from connecting to the Internet. There is also the issue of port forwarding rules for your firewall. Without defining which port the data should go through, you can do none of these things. Also, as part of added security measures, you may have to change the default SSH port, adding an extra challenge to any would-be hackers. The Secure Shell connection uses a specific port that has to be opened by the firewall. Of course, there is the most well-known use of port forwarding, the SSH connection.

Together, they provide an extra layer of security against hackers or DDoS (direct denial of service) attacks. This is made even safer by your firewall, which effectively blocks all but a few ports, stopping communication. If a host on the external network wants to connect to one of your devices on the internal network, it has to know what IP address and port that device is using to connect to the router. Standing between the two are routers or Network Address Translators, which allow internal computers to communicate with outside services (like web services) while staying hidden. These are, of course, external addresses (and ports, when communication is involved). On the Internet, however, there are servers and routers and other devices and these are identified with a set of unique, fixed IP addresses. Most of these addresses are by default something like 192.168.1.1, meaning they are far from unique. But all these are internal addresses, valid only in your Local Area Network (LAN). Each of these has its own IP address and each communicates using different ports. Your local network, for example, is made up of your laptop, your printer, a webcast device, a smart TV, your WiFi-connected phone, etc. You may also want to change the remote desktop port for your Windows VPS. While an IP address is a way to find individual devices, a port identifies the services or applications that the device is running on the network. Why would anyone want to do that? It’s because one of the two pairs is external and the other internal. On paper, at least, port forwarding is easy enough to define: it’s mapping an IP address and port number to another IP address and another port number. Port forwarding may seem a complicated concept from a user’s nightmares or as simple as a few clicks, depending on what you are going to do with it. 4 You’re Done - or Are You?
