I would like to see if it can be changed to 5 seconds. Thanks, Configuring a VPN Policy with IKE using Preshared Secret Select Enable Keep Alive to use heartbeat messages between peers on this VPN tunnel. If one end of the tunnel fails, using KeepAlive will allow for the automatic renegotiation of the tunnel once both sides become available again without having to wait for the proposed Life Time to expire.

Since Permanent Tunnels are constantly monitored, if the VPN tunnel is down, then a log, alert, or user defined action, can be issued. A VPN tunnel is monitored by periodically sending "tunnel test" packets. As long as responses to the packets are received the VPN tunnel is considered "up."
