Virtual Private Network (VPN) is basically of TWO types:
Remote Access VPN
Remote Access VPN permits a user to connect to a private network and access all its services and resources remotely like file sharing and printing, Software Applications etc. The connection between the user and the private network establish through the Internet and the connections are secure and private. Remote Access VPN is useful for home users and business users both.An employee of a company, while not in office, uses a VPN connection to their company’s private network and remotely access files and resources on the private network. Private users or home users of VPN, primarily use VPN services to bypass regional restrictions on the Internet and access blocked websites. Users aware of Internet security also use VPN services to enhance their Internet security and privacy.
Site to Site VPN
A Site-to-Site VPN is also called as Router-to-Router VPN and is commonly used in the large companies. Companies or organizations, with branch offices or different locations, use Site-to-site VPN to connect the network of one office location to the network at another office location.Basically, Site-to-site VPN create an imaginary bridge between the networks at geographically distant offices and connect them through the Internet and sustain a secure and private communication between the networks. In Site-to-site VPN one router acts as a VPN Client and another router as a VPN Server as it is based on Router-to-Router communication. When the authentication is validated between the two routers only then the communication starts.
