Connectivity Check The interface can regularly check the connection to the gateway you specified
to make sure it is still available. You specify how often the interface checks the
connection, how long to wait for a response before the attempt is a failure, and
how many consecutive failures are required before the ZyWALL stops routing to
the gateway. The ZyWALL resumes routing to the gateway the first time the
gateway passes the connectivity check.
