Virtual Private Networking
This chapter describes how to use the virtual private networking (VPN) features of the ADSL2+
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 6-1
provides an overview of the two most
common VPN configurations: client-to-gateway and gateway-to-gateway.
•
“Planning a VPN” on page 6-3
provides 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 6-4
summarizes the three ways to configure a VPN
tunnel: VPN Wizard (recommended for most situations), Auto Policy, and Manual Policy.
•
“Setting Up a Client-to-Gateway VPN Configuration” on page 6-5
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 6-18
provides the steps
needed to configure a VPN tunnel between two network gateways using the VPN Wizard.
•
“VPN Tunnel Control” on page 6-25
provides the step-by-step procedures for activating,
verifying, deactivating, and deleting a VPN tunnel once the VPN tunnel has been configured.
•
“Setting Up VPN Tunnels in Special Circumstances” on page 6-32
provides 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.
Overview of VPN Configuration
Two common scenarios for configuring VPN tunnels are between a remote PC and a network
gateway; and between two or more network gateways. The DG834G v5 supports both of these
types of VPN configurations. The DG834G v5 supports up to five concurrent tunnels.
