Configure advanced site-to-site VPN settings.
Option Description Dead peer detection
Dead peer detection (DPD) identifies inactive or unavailable IKE peers. Using IPsec traffic patterns, DPD can use a minimal number of IKE messages to confirm whether the connection is live. DPD is used to restore resources that are lost when a peer is unavailable. Selecting Enable dead peer detection reestablishes VPN tunnels on idle connections and cleans up dead VPN peers if required.
IKE Debugging
Enable or disable IKE debugging.
