nodes.

route-based VPNs nodes.

Define Security Protocol (Encryption and Authentication)

How do you want to protect the VPN traffic?
Autokey IKE
L2TP
L2TP over AutoKey IKE
Manual Key (you cannot use VPN Manager to create a Manual Key VPN)
You must also decide if you want to use certificates to authenticate communication
between the VPN members.

Define Method: VPN Manager or Device-Level?

How do want to create the tunnel? Using VPN Manager or configuring each device?
Using VPN Manager
When adding a VPN using the VPN Manager, you enter the VPN members, gateways, IKE
properties, and VPN topology, then autogenerate the VPN rules that create the VPN. You
can inspect the VPN rules and override any VPN property before sending the VPN
configuration to your devices.
