Overview of VPN Configuration
Two common scenarios for configuring VPN tunnels are between a remote personal computer and
a network gateway and between two or more network gateways. The FVS114 supports both of
these types of VPN configurations. The FVS114 VPN Firewall supports up to eight 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 (see Figure 5-1).
Figure 5-1: Client-to-gateway VPN tunnel
A VPN client access allows a remote PC to connect to your network from any location on the
Internet. In this case, the remote PC is one tunnel endpoint, running the VPN client software. The
FVS114 VPN Firewall on your network is the other tunnel endpoint. See “How to Set Up a
Client-to-Gateway VPN Configuration” on page 5-5 to set up this configuration.

Gateway-to-Gateway VPN Tunnels

Gateway-to-gateway VPN tunnels provide secure acce ss between networks, such as a branch
or home office and a main office (see Figure 5-2).
