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.
For DPD to function, the peer VPN device on the other end of the tunnel must also support
DPD. Keep-alive, though less reliable than DPD, does not require any support from the peer
device.
