The Dead Peer Detection (DPD) feature lets the VPN firewall maintain the IKE SA by 
exchanging periodic messages with the remote VPN peer. 

Enable Keepalive

Select the Yes radio button to enable the keep-alive feature. Periodically, the 
VPN firewall sends keep-alive requests (ping packets) to the remote endpoint to 
keep the tunnel alive. You must specify the ping IP address in the Ping IP 
Address field, the detection period in the Detection Period field, and the 
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.

Reconnect after 
failure count

The maximum number of keep-alive requests before the VPN 
firewall tears down the connection and then attempts to 
reconnect to the remote endpoint. The default setting is 3 
keep-alive requests.
