maximum number of keep-alive requests that the VPN firewall sends in the
Reconnect after failure count field.
Ping IP Address The IP address that the VPN firewall pings. The address
must be of a host that can respond to ICMP ping requests.
Detection Period The period in seconds between the keep-alive requests. The
default setting is 10 seconds.

The maximum number of keep-alive requests before the VPN
firewall tears down the connection and then attempts to

keep-alive requests.
