Overview of VPN Configuration
Two common scenarios for VPN tunnels are between a remote PC and a network gateway,
and between two or more network gateways. The N600 Wireless Dual Band Gigabit ADSL2+
Modem Router DGND3700 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 PC, such as a
telecommuter connecting to an office network.

A VPN client access allows a remote PC to connect to your network from any location on the
Internet. The remote PC is one tunnel endpoint, running the VPN client software. The
wireless modem router on your network is the other tunnel endpoint. See Set Up a
Client-to-Gateway VPN Configuration on page
90 for information about how to set up this
configuration.
Gateway-to-Gateway VPN Tunnels
Gateway-to-gateway VPN tunnels provide secure access between networks, such as a
