Configure Keep-alives and Dead Peer Detection

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.

For DPD to function, the peer VPN device on the other end of the tunnel should also support

DPD. Keep-alive, though less reliable than DPD, does not require any support from the peer

device.
