IKE with AES-128 (Side #1)
Posted by , Last modified by Daniel Lizaola on 22 November 2017 01:35 PM

The command sequence below defines a VPN Tunnel that uses AES-128 to route traffic from Side #1 (192.168.1.0) to Side #2 (192.168.2.0).

NOTE:

-You must replace ‹X.X.X.X› in the template with the IP address for Side #2.

-You must replace ‹MySharedKey› in the template with text string as the initial shared key

-You must replace ‹nnnn› in the template with unique number from 1-99999 like 12345

-You must purchase the appropriate software license for your SmartNode to support VPN service. To see the current licenses active for your SmartNode, execute the "show license" command.
