• IKE Keep Alive. If you want to ensure that a connection is kept open, or, if that is not

The ping IP address has to be associated with the remote endpoint. You have to use the

remote LAN address. This IP address will be pinged periodically to generate traffic for the

VPN tunnel. The remote keep-alive IP address needs to be covered by the remote LAN

IP range and to correspond to a device that can respond to a ping. The range should be

made as narrow as possible to meet this objective.
