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 DGN2200 supports both types. The
DGN2200 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 modem
router on your network is the other tunnel endpoint. (See Set Up a Client-to-Gateway VPN
Configuration on page 98.)
Gateway-to-Gateway VPN Tunnels
Gateway-to-gateway VPN tunnels provide secure access between networks, such as a
branch or home office and a main office.
