provide the requested services.
To create a VPN tunnel using the IPSec protocol, perform the following

tunnel from the Attachment Layer drop-down menu. The VPN

If you selected WAN Interface as your attachment layer, select the

Attachment Interface drop-down
menu.
If you selected PPP Profile as your attachment layer, select the appropriate
PPP profile in the
Attachment Profile drop-down menu.
