Chapter 5
Basic Virtual Private Networking
This chapter describes how to use the virtual private networking (VPN) features of the VPN
firewall. VPN communications paths are called tunnels. VPN tunnels provide secure, encrypted
communications between your local network and a remote network or computer.
The VPN information is organized as follows:
•
“Overview of VPN Configuration” on page 5-2
provides an overview of the two most
common VPN configurations: client-to-gateway and gateway-to-gateway.
•
“Planning a VPN” on page 5-3
provides the VPN Committee (VPNC) recommended default
parameters set by the VPN Wizard.
•
“VPN Tunnel Configuration” on page 5-4
summarizes the two ways to configure a VPN
tunnel: VPN Wizard (recommended for most situations) and Advanced (see
Chapter 6,
“Advanced Virtual Private Networking
).
•
“Setting Up a Client-to-Gateway VPN Configuration” on page 5-5
provides the steps needed
to configure a VPN tunnel between a remote PC and a network gateway using the VPN
Wizard and the NETGEAR ProSafe VPN Client.
•
“Setting Up a Gateway-to-Gateway VPN Configuration” on page 5-19
provides the steps
needed to configure a VPN tunnel between two network gateways using the VPN Wizard.
•
“Activating a VPN Tunnel” on page 5-23
provides the step-by-step procedures for activating,
verifying, deactivating, and deleting a VPN tunnel once the VPN tunnel has been configured.
•
Chapter 6, “Advanced Virtual Private Networking
” provides the steps needed to configure
VPN tunnels when there are special circumstances and the VPNC recommended defaults of
the VPN Wizard are inappropriate.
•
Appendix B, “Related Documents
” has a link to
“Virtual Private Networking (VPN)
” which
discusses Virtual Private Networking (VPN) Internet Protocol security (IPSec). IPSec is one of
the most complete, secure, and commercially available, standards-based protocols developed
for transporting data.
•
Appendix C, “VPN Configuration of NETGEAR FVG318
” presents a case study on how to
configure a secure IPSec VPN tunnel from a NETGEAR FVG318 to a FVL328. This case
study follows the VPN Consortium interoperability profile guidelines (found at
).

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 FVG318 supports both of
these types of VPN configurations. The 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
).
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
VPN firewall on your network is the other tunnel endpoint. See
“Setting 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 access between networks, such as a branch or
home office and a main office (see
Figure 5-2
).
