Advanced VPN Settings
• Enable IKE Dead Peer Detection - Select if you want inactive VPN tunnels to be dropped by the
SonicWALL.
Dead Peer Detection Interval - Enter the number of seconds between “heartbeats” in the Dead
peer detection Interval (seconds) field. The default value is 60 seconds.
Failure Trigger Level (missed heartbeats) - Enter the number of missed heartbeats in the
Failure Trigger Level (missed heartbeats) field. The default value is 3. If the trigger level is
reached, the VPN connection is dropped by the SonicWALL security appliance. The SonicWALL
security appliance uses a UDP packet protected by Phase 1 Encryption as the heartbeat.
• Enable Dead Peer Detection for Idle VPN Sessions - Select this setting if you want idle VPN
connections to be dropped by the SonicWALL security appliance after the time value defined in
the Dead Peer Detection Interval for Idle VPN Sessions (seconds) field. The default value is
600 seconds (10 minutes).
