Enable Connectivity Check Check Method 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. Select this to turn on the connection check. 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 Check this address Check Port Check these addresses Probe Succeeds When Select tcp to have the Zyxel Device regularly perform a TCP handshake with the gateway you specify to make sure it is still available.
