Reference Manual for the ADSL Modem Router DG834 v3
Virtual Private Networking (Advanced Feature) 6-3
v1.1, October 2006
A VPN between two or more NETGEAR VPN-enabled routers 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 DG834 v3s on each end of the tunnel to form the
VPN tunnel end points. See “How to Set Up a Gateway-to-Gateway VPN Configuration” on
page 6-20 to set up this configuration.
Planning a VPN
When you set up a VPN, it is helpful to plan the network configuration and record the
configuration parameters on a worksheet:
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.
