Network administrators have numerous choices when it comes to deploying a VPN that include the following.

Remote access VPN
Remote access clients connect to a VPN gateway server on the administration's network. The gateway requires the device to authenticate its identity before granting access to internal network resources. This type usually relies on either IPsec or SSL to secure the connection.

Site-to-site VPN
Site-to-site VPN uses a gateway device to connect an entire network in one location to a network in another location. End-node devices in the remote location do not need VPN clients because the gateway handles the connection. Most site-to-site VPNs connecting over the internet use IPsec. It is also common for them to use carrier Multiprotocol Label Switching (MPLS) connections rather than the public internet as the transport for site-to-site VPNs. It is possible to have either Layer 3 connectivity or Layer 2 (virtual private local area network service) running across the base transport links.

Mobile VPN
In a mobile VPN, the server still sits at the edge of the organization's network, enabling secure tunneled access by authenticated, authorized clients. Mobile VPN tunnels are not tied to physical IP addresses, however. Instead, each tunnel is bound to a logical IP address. That logical IP address stays to the mobile device. An effective mobile VPN provides continuous service to users and can switch across access technologies and multiple public and private networks.
