VPN Tunnel Configuration
There are two tunnel configurations and three ways to configure them:
• Use the VPN Wizard to configure a VPN tunnel (recommended for most situations):
— See “How to Set Up a Client-to-Gateway VPN Configuration” on page 6-6.
— See “How to Set Up a Gateway-to-Gateway VPN Configuration” on page 6-20.
• See “Using Auto Policy to Configure VPN Tunnels” on page 6-36 when the VPN Wizard and
its VPNC defaults (see Table 6-2 on page 6-4) are not appropriate for your special
circumstances, but you want to automate the Internet Key Exchange (IKE) setup.
• See “Using Manual Policy to Configure VPN Tunnels” on page 6-46 when the VPN Wizard
and its VPNC defaults (see Table 6-2 on page 6-4) are not appropriate for your special
circumstances and you must specify each phase of the connection. You manually enter all the
authentication and key parameters. You have more control over the process, however the
process is more complex and there are more opportunities for errors or configuration
mismatches between your DG834 v3 and the corresponding VPN endpoint gateway or client
workstation.
Note: NETGEAR publishes additional interoperability scenarios with various gateway
and client software products. Look on the NETGEAR web site at
www.netgear.com for these interoperability scenarios.
