One of the most common techniques out there for people with a remote desktop is port forwarding. This allows remote computers to access a local area network (LAN) or specific router fr om an outside location. This technique is extremely useful if you are on the go a lot but want to keep using a specific network. It is especially useful to small businesses, which use it to connect satellite offices, provide remote access to employees on the move, and more.
What is Port Forwarding?
Port forwarding, also known as port mapping, is intended to open up access to network services for specific computers that are directly on a network. Typically, somebody logging onto the Internet actually has two IP addresses – the general address used by the Internet router and the specific, hidden address used by the specific computer. The computer feeds information to the router, which then handles all incoming and outgoing information. Port forwarding allows you to open up new channels on your router that allows the flow of information in different ways. Local port forwarding can be used to overcome firewalls for certain services, while remote forwarding can give outside access to chosen machines.
