VPN Routers
VPN support
— support for the VPN function of the router — virtual private networks. One of the key principles behind this feature is the transmission of encrypted data over open networks, primarily the Internet. A VPN is used mainly in two formats:- Creating virtual networks based on an Internet connection. Thus, it is possible, for example, to combine branches of one company located in different cities or even countries into one logical network. At the same time, thanks to traffic encryption, the entire network remains closed to outsiders, although data is transmitted over an open channel. For this format, devices of the Firewall type (see "Type") are mainly used, while such a device actually plays the role of a VPN server.
- Internet connection through an external VPN server. The functions of such a server are in many ways similar to a proxy: it serves as an "intermediary" in the exchange of traffic and replaces the user's IP address with its own address. The latter, in particular, allows you to bypass regional restrictions: nowadays, servers with IP addresses related to almost any country in the world are available. However, a VPN server, unlike a proxy, additionally encrypts the traffic transmitted to the user — this, again, has a positive effect on security and privacy. This mode is also available in regular routers.
