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. Enable Connectivity Check Select this to turn on the connection check. Check Method Select the method that the gateway allows. Select icmp to have the Zyxel Device regularly ping the gateway you specify to make sure it is still available. Check Period Check Timeout Check Fail Tolerance Check Default Gateway Select tcp to have the Zyxel Device regularly perform a TCP handshake with the gateway you specify to make sure it is still available. Enter the number of seconds between connection check attempts. Enter the number of seconds to wait for a response before the attempt is a failure. Enter the number of consecutive failures before the Zyxel Device stops routing through the gateway. Select this to use the default gateway for the connectivity check.
