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.

A VPN between two or more NETGEAR VPN-enabled firewalls is a good way to connect branch
or home offices and business partners over the Internet. VPN tunnels also enable access to network
resources across the Internet. In this case, use FVG318s on each end of the tunnel to form the VPN
tunnel end points. See
to set up this configuration.

Planning a VPN

To set up a VPN connection, you must configure each endpoint with specific identification and
connection information describing the other endpoint. You must configure the outbound VPN
settings on one end to match the inbound VPN settings on other end, and vice versa.
This set of configuration information defines a security association (SA) between the two VPN
endpoints. When planning your VPN, you must make a few choices first:
• Will the local end be any device on the LAN, a portion of the local network (as defined by a
subnet or by a range of IP addresses), or a single PC?
• Will the remote end be any device on the remote LAN, a portion of the remote network (as
defined by a subnet or by a range of IP addresses), or a single PC?
