Overview of VPN Configuration
Two common scenarios for VPN tunnels are between a remote computer and a network
gateway, and between two or more network gateways. The modem router supports both
types. It supports up to five concurrent tunnels.
Client-to-Gateway VPN Tunnels
Client-to-gateway VPN tunnels provide secure access from a remote computer, such as a
telecommuter connecting to an office network.

A VPN client access allows a remote computer to connect to your network from any location
on the Internet. The remote computer is one tunnel endpoint, running the VPN client
software. The modem router on your network is the other tunnel endpoint. See
