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 4-2 provides an overview of the two most
common VPN configurations: client-to-gateway and gateway-to-gateway.
• “Planning a VPN” on page 4-3 provides the VPN Committee (VPNC) recommended default
parameters set by the VPN Wizard.
• “VPN Tunnel Configuration” on page 4-5 summarizes the two ways to configure a VPN
tunnel: VPN Wizard (recommended for most situations) and Advanced (see Chapter 5,
“Advanced Virtual Private Networking).
• “Setting Up a Client-to-Gateway VPN Configuration” on page 4-5 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 4-21 provides the steps
needed to configure a VPN tunnel between two network gateways using the VPN Wizard.
• “Activating the VPN Tunnel” on page 4-27 provides the step-by-step procedures for
activating, verifying, deactivating, and deleting a VPN tunnel once the VPN tunnel has been
configured.
• Chapter 5, “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.
• “Virtual Private Networking (VPN)” in Appendix B, “Related Documents” 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.
