and authentication for communication between two or more parties. In essence, IKE manages
IPSec keys automatically for the parties.
To configure IKE key settings for the Mobility 7131 Access Point:
1. Select Network Configuration -> WAN -> VPN from the Mobility 7131 Access Point menu tree.
2. Refer to the VPN Tunnel Config field, select the Auto (IKE) Key Exchange radio button and click
the IKE Settings button.
