If creating a new IKE policy, assign it a 32 character maximum name to help
differentiate this IKE configuration from others with a similar parameters.
Configure the IKE keep alive message interval used for dead peer detection
on the remote end of the IPSec VPN tunnel. Set this value in either Seconds
(10 - 3,600), Minutes (1 - 60) or Hours (1). The default setting is 30 seconds.
This setting is required for both IKEv1 and IKEV2.
If using IKEv1, use the drop-down menu to define the IKE mode as either
Main or Aggressive. IPSEC has two modes in IKEv1 for key exchanges.
Aggressive mode requires 3 messages be exchanged between the IPSEC
peers to setup the SA, Main requires 6 messages. The default setting is
Main.
Use the spinner control to set the maximum number of keep alive messages
sent before a VPN tunnel connection is defined as dead. The available range
is from 1 - 100. The default setting is 5.
