MTU Maximum Transmission Unit. Type the maximum size of each data
packet, in bytes, that can move through this interface. If a larger

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.
