For one, it can help mask public IP address and restricts unauthorized access to resources on a private network, which in turns cloaks your network resources (i.e. Well that is because this additional process helps mask your original IP address.Īside from online gaming and boosting downloading speeds, Port forwarding has a lot if security and privacy benefits as well. Now you might be wondering why send data packets to a different resource other than the intended one. If you configure it in your router or use the built in port forwarder of your VPN client then it will automatically jot down all the original destination headers and rewrite them before forwarding them to an intermediary host resource (computer/ server). Typically, routers handle all the work related to data packets, in a sense, which packets needs to travel where, however port forwarding handles things a bit differently. If you do not know what a header is, it is basically an address file, which contains the origin and destination IP addresses. A data packet is a payload, which contains your data along with header information. Just as emails need an address to communicate, computers need data packets for successful delivery. In order for computers to communicate online, they need some sort of information. However, if you are unfamiliar with the concept and how you can setup port forwarding yourself, you’ll find all answers in the passages below.
You might have even used port forwarding in order to access certain online gaming servers. The rationale behind port forwarding is to increase security by keeping undesired traffic outside of your network. This can be implemented either through software that take care of the redirection automatically or by adding a piece of hardware such as a router in your networking topology. Port forwarding, as the name implies, is a networking technique that redirects internet traffic bound for a certain IP/port combination to a different IP/port combination.
