About Remote Access

A virtual private network (VPN) is a private network that interconnects remote (and often geographically separate) networks through primarily public communication infrastructures such as the Internet. VPNs provide security through tunneling protocols and security procedures such as encryption. For example, a VPN could be used to securely connect the branch offices of an organization to a head office network through the public Internet. A VPN can also be used to interconnect two similar-type networks over a dissimilar middle network for example, two IPv6 networks over an IPv4 network . There are two main types of VPN: remote-access VPNs and Site-to-site VPNs. Remote-access VPNs allow individual users to connect to a remote network such as roaming salespeople connecting to their company's intranet. Site-to-site VPNs allow inter-connection of networks of multiple users for example, branch offices to the main company network.
