Get
Automatically
This option appears when Interface Properties is External or
General. Select this to make the interface a DHCP client and
automatically get the IP address, subnet mask, and gateway address
from a DHCP server.
You should not select this if the interface is assigned to a VRRP group.
See Chapter 39 on page 713.
Use Fixed IP
Address
This option appears when Interface Properties is External or
General. Select this if you want to specify the IP address, subnet
mask, and gateway manually.
IP Address Enter the IP address for this interface.
Subnet Mask Enter the subnet mask of this interface in dot decimal notation. The
subnet mask indicates what part of the IP address is the same for all
computers in the network.
Gateway This option appears when Interface Properties is External or
General. Enter the IP address of the gateway. The ZyWALL sends
packets to the gateway when it does not know how to route the
packet to its destination. The gateway should be on the same network
as the interface.
Metric 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.
Interface
Parameters
Egress
Bandwidth
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.
Ingress
Bandwidth
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.
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 - 1500. Usually, this value is 1500.
Connectivity
Check
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.
