In some cases, you might not want a VPN tunnel to be disconnected when traffic is idle, for
example, when client-server applications over the tunnel cannot tolerate the tunnel
establishment time. If you require a VPN tunnel to remain connected, you can use the
keep-alive and Dead Peer Detection (DPD) features to prevent the tunnel from being
disconnected and to force a reconnection if the tunnel disconnects for any reason.
