Netgear FVS318v3 – Cable/DSL ProSafe VPN Firewall with 8-Port Switch Reference Manual

Basic Virtual Private Networking

4-3

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 FVS318v3s on each end of the tunnel to form the 
VPN tunnel end points. See 

to set up this configuration.

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?

•

Will either endpoint use Fully Qualified Domain Names (FQDNs)? Many DSL accounts are 
provisioned with DHCP addressing, where the IP address of the WAN port can change from 
time to time. Under these circumstances, configuring the WAN port with a dynamic DNS 
(DynDNS) service provider simplifies the configuration task. When DynDNS is configured on 
the WAN port, configure the VPN using FDQN.
