What is port forwarding?

Have you heard about port forwarding and what does port forwarding do? Briefly, Port forwarding is an application of network address translation that allows a remote PC to connect to a PC on a private local area network(LAN), which makes it possible for those who have the need to remote access a PC over the internet with RDP. For example, if your friend needs to control your PC remotely, but you are not on the same LAN. Then he or she can port forward to create RDP.

What is Port Forwarding

Is port forwarding safe?

Many users are curious about the security of the port forwarding at the same time, worrying about the router will be accessed by the hacker and the specific external IP will be hacked. Is port forwarding dangerous? Actually, port forwarding is, for the most part, safe. The situation that your router permits outside machines to connect to a machine on your network is known as port forwarding. It doesn't provide you with any special access to the router's internals. And all it gives you is a link to your internal workstation, where you configure the router and feed it a certain port number.

Moreover, as long as your computer or network has a security firewall or a VPN connection, the entire operation of port forwarding is safe. And it relies on your network's security and the specific ports you're utilizing, so, port forwarding isn't that dangerous.

Remote access computer over internet without port forwarding

Is port forwarding safe? Absolutely! But aren’t you feel too complicated to port forwarding for remote access over Internet? And we may meet with all kinds of issues when we port forward like some users can’t log in to the router, some RDP errors appear after changing the port number, and so on. If the purpose of port forwarding is to connect remotely without being on the same LAN, then why not use a more useful and convenient remote access software-- AnyViewer.

AnyViewer actually realizes remote control anywhere, anytime, without being confined to remote access on the same LAN or finding the IP address and user name of the remote PC. Furthermore, on Windows 11/10/8.1/8/7 and Windows Server 2022/2019/2016/2012 R2, the fast connection speed, and techniques for attended and unattended access, respectively, can provide a novel experience.
