Select a radio button to specify if keep-alive is enabled:
• Yes. This feature is enabled: Periodically, the UTM sends keep-alive
requests (ping packets) to the remote endpoint to keep the tunnel alive. You
need to 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 UTM sends in the Reconnect after failure count
field.
• No. This feature is disabled. This is the default setting.
Ping IP Address The IP address that the UTM pings. The address needs to
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

UTM tears down the connection and then attempts to
reconnect to the remote endpoint. The default setting is
3 keep-alive requests.
