Overview
A virtual private network (VPN) consists of at least one VPN server or
gateway, and several VPN clients. A VPN server makes the office network
remotely available to authorized users, such as employees working from
home, who connect to the VPN server using VPN clients. A VPN gateway
can be connected to another VPN gateway in a permanent, bi-directional
relationship. The two connected networks function as a single network.
A connection between two VPN sites is called a VPN tunnel. VPN tunnels
encrypt and authenticate all traffic passing through them. Through these
tunnels, employees can safely use their company’s network resources when
working at home. For example, they can securely read email, use the
company’s intranet, or access the company’s database from home.
