Virtual Private Networking

This chapter describes how to use the virtual private networking (VPN) features of the ADSL Modem Wireless Router. VPN communications paths are called tunnels. VPN tunnels provide secure, encrypted communications between your local network and a remote network or computer. See “Virtual Private Networking (VPN)” in Appendix C to learn more about VPN.

This chapter is organized as follows:

“Overview of VPN Configuration” on page 8-2provides an overview of the two most common VPN configurations: Client-to-Gateway and Gateway-to-Gateway.

“Planning a VPN” on page 8-4provides a worksheet for recording the configuration parameters of the VPN you want to set up, along with the VPN Committee (VPNC) recommended default parameters set by the VPN Wizard.

“VPN Tunnel Configuration” on page 8-6summarizes the three ways to configure a VPN tunnel: VPN Wizard (recommended for most situations), Auto Policy, and Manual Policy.

“How to Set Up a Client-to-Gateway VPN Configuration” on page 8-7provides 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.

“How to Set Up a Gateway-to-Gateway VPN Configuration” on page 8-21provides the steps needed to configure a VPN tunnel between two network gateways using the VPN Wizard.

“VPN Tunnel Control” on page 8-29provides the step-by-step procedures for activating, verifying, deactivating, and deleting a VPN tunnel once the VPN tunnel has been configured.

“How to Set Up VPN Tunnels in Special Circumstances” on page 8-38provides the steps needed to configure VPN tunnels when there are special circumstances and the VPNC recommended defaults of the VPN Wizard are inappropriate. The two alternatives for configuring VPN tunnels are Auto Policy and Manual Policy.
