DG834 Manual: How to Set Up VPN Tunnels in Special Circumstances

When the VPN Wizard and its VPNC defaults (see Table 6-2.) are not appropriate for your special circumstances, use one of the following alternatives:

Auto Policy-for a typical automated Internet Key Exchange (IKE) setup, see Using Auto Policy to Configure VPN Tunnels. Auto Policy uses the IKE protocol to define the authentication scheme and automatically generate the encryption keys.

Manual Policy-for a Manual Keying setup in which you must specify each phase of the connection, see Using Manual Policy to Configure VPN Tunnels. Manual Policy does not use IKE. Rather, 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 and the corresponding VPN endpoint gateway or client workstation.
