Virtual Private Networking Using IPsec
This chapter describes how to use the IPsec virtual private networking (VPN) features of the
ProSafe VPN Firewall to provide secure, encrypted communications between your local network
and a remote network or computer.
This chapter contains the following sections:
• “Using the VPN Wizard for Client and Gateway Configurations” on page 5-1
• “Testing the Connections and Viewing Status Information” on page 5-11
• “Managing VPN Policies” on page 5-14
• “Configuring Extended Authentication (XAUTH)” on page 5-17
• “Assigning IP Addresses to Remote Users (ModeConfig)” on page 5-21
• “Configuring Keepalives and Dead Peer Detection” on page 5-27
• “Configuring NetBIOS Bridging with VPN” on page 5-29
Using the VPN Wizard for Client and Gateway Configurations
You use the VPN Wizard to configure multiple gateway or client VPN tunnel policies.
The section below provides wizard and NETGEAR VPN Client configuration procedures for the
following scenarios:
• Using the wizard to configure a VPN tunnel between 2 VPN gateways
• Using the wizard to configure a VPN tunnel between a VPN gateway and a VPN client
Configuring a VPN tunnel connection requires that all settings and parameters on both sides of the
VPN tunnel match or mirror each other precisely, which can be a daunting task. The VPN Wizard
efficiently guides you through the setup procedure with a series of questions that will determine
the IPsec keys and VPN policies it sets up. The VPN Wizard will also set the parameters for the
network connection: Security Association, traffic selectors, authentication algorithm, and
encryption. The parameters used by the VPN wizard are based on the recommendations of the
VPN Consortium (VPNC), an organization that promotes multi-vendor VPN interoperability.
