DPD Idle Period The DPD protocol defines a worry period. This is an idle time during which no IPSec traffic is detected from the remote peer. At the expiry of this period the local peer transmits a number of R-U-THERE messages to detect the liveliness of the remote peer.

This option sets the duration of the idle period, expressed in seconds.

dpd_idle_period	Unit	default value
	seconds	180

DPD number of Transmits

This option determines the number of R-U-THERE transmitted by the local peer. If none of these messages is acknowledged in due time by the remote peer, it is decided that the remote peer is dead.

dpd_xmits	default value
	3

DPD Timeout This option determines the timeout value for the R-U-THERE messages. Within this period an R-U-THERE acknowledge message from the remote peer is expected.

dpd_timeout	Unit	default value
	seconds	120

Tunnel inactivity timeout When no traffic is detected at the peer for a certain period, it is decided that the tunnel is not used any more, and the IKE session is terminated. All IPSec connections supported by the IKE session are terminated as well.

This option sets the value of the inactivity timer.

inactivity	Unit	default value
	seconds	3600
