DESCRIPTION
Select On button to turn on stac compression, and select Off to turn
off stac compression. Stac compression is a data compression
technique capable of compressing data by a factor of about four.
Type the number of seconds the ZyWALL should wait for traffic before
it automatically disconnects the connection. Set this field to zero to
disable the idle timeout. Allowed values are 0 - 360.
Click Advanced to display more settings. Click Basic to display fewer
settings.
Select this if this interface is a DHCP client. In this case, the DHCP
server configures the IP address automatically. The subnet mask and
gateway are always defined automatically in PPPoE/PPTP interfaces.
Select this if you want to specify the IP address manually.
This field is enabled if you select Use Fixed IP Address.
Enter the IP address for this interface.
Enter the priority of the gateway (the ISP) 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 - 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.
