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.
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.
Select this to turn on the connection check.
Select the method that the gateway allows.
Select icmp to have the ZyWALL regularly ping the gateway you specify to make sure it
is still available.
Select tcp to have the ZyWALL 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 ZyWALL stops routing through the
gateway.
Select this to use the default gateway for the connectivity check.
