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 Zyxel Device stops routing to the gateway. The Zyxel Device
resumes routing to the gateway the first time the gateway passes the connectivity check.
