DESCRIPTION
This option appears when Interface Properties is External or
General. Enter the priority of the gateway (if any) on this interface.
The ZyWALL decides which gateway to use based on this priority. The
lower the number, the higher the priority. If two or more gateways
have the same priority, the ZyWALL uses the one that was configured
first.
Enter the maximum amount of traffic, in kilobits per second, the
ZyWALL can send through the interface to the network. Allowed
values are 0 - 1048576.
This is reserved for future use.
Enter the maximum amount of traffic, in kilobits per second, the
ZyWALL can receive from the network through the interface. Allowed
values are 0 - 1048576.
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 - 1500. Usually, this value is 1500.
These fields appear when Interface Properties is External or
General.
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.
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.
Select this to specify a domain name or IP address for the
connectivity check. Enter that domain name or IP address in the field
next to it.
