Dead Peer Detection allows the tunnel to be restarted if the remote gateway stops responding. This
option will only have an effect if the remote gateway supports Dead Peer Detection. It operates by
sending notifications and waiting for acknowledgements. Delay is the time between notifications.
The tunnel will be restarted if no acknowledgements have been received for a period of Timeout.
The recommended keying used in IPSec is Automatic Keying (IKE). The default and recommended
method of authentication is through a Pre-Shared Secret. A Pre-Shared Secret should be at least 24
characters long, and should be a phrase you can remember easily but would be difficult for others to
guess. Authentication can also be achieved using RSA Digital Signatures.
Click Add to complete the IKE setup.
