VPN gateway definition
A VPN gateway is a networking device that connects other devices and networks into a single VPN infrastructure. It can be used to establish communication between remote offices, connect two networks or devices together, and even combine multiple VPNs together into a single network.
A VPN gateway device must have internetworking and data transmission functions. It can be configured to allow, block, or reroute VPN traffic. VPN gateways provide networking services that are specific to VPNs, like assigning and managing IP addresses or static and dynamic routing of routing tables and their maintenance. A VPN gateway can be a server, a firewall, or most commonly, a router.
