MTU Maximum Transmission Unit. Type the maximum size of each data packet, in bytes,
that can move through this interface. If a larger packet arrives, the ZyWALL divides it
into smaller fragments. Allowed values are 576 - 1492. Usually, this value is 1492.
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.
