• When the VPN Wizard and its VPNC defaults (see Table 4 on page 102) are not
appropriate for your special circumstances, but you want to automate the Internet Key
Exchange (IKE) setup, see Use Auto Policy to Configure VPN Tunnels on page 124.
• When the VPN Wizard and its VPNC defaults (see Table 4 on page 102) are not
appropriate for your special circumstances and you have to specify each phase of the
connection, see Use Manual Policy to Configure VPN Tunnels on page 131. 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 N600 Wireless Dual Band Gigabit
VDSL2 Modem Router DGND3800B and the corresponding VPN endpoint gateway or
client workstation.
