LABEL DESCRIPTION
Ethernet Interface
Properties
Enable Select this to enable this interface. Clear this to disable this interface.
Interface Name This field is read-only. This is the name of the Ethernet interface.
Description Enter a description of this interface. It is not used elsewhere. You can use
alphanumeric and
()+/:=?!*#@$_%- characters, and it can be up to 60
characters long.
IP Address
Assignment
These IP address fields configure an IP address on the interface itself. If you
change this IP address on the interface, you may also need to change a related
address object for the network connected to the interface. For example, if you
use this screen to change the IP address of your LAN interface, you should also
change the corresponding LAN subnet address object.
Get
Automatically
Select this if this interface is a DHCP client. In this case, the DHCP server
configures the IP address, subnet mask, and gateway automatically.
You should not select this if the interface is assigned to a VRRP group. See
Chapter 33 on page 493.
Use Fixed IP
Address
Select this if you want to specify the IP address, subnet mask, and gateway
manually.
IP Address This field is enabled if you select Use Fixed IP Address.
Enter the IP address for this interface.
Subnet Mask This field is enabled if you select Use Fixed IP Address.
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 field is enabled if you select Use Fixed IP Address.
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 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.
