DESCRIPTION

General Settings

 

 

 

Enable Interface

Select this to enable this interface. Clear this to disable this interface.

 

 

Interface Properties

 

 

 

Interface Name

This field is read-only. This is the name of the Ethernet interface.

 

 

Port

This field is read-only. This is the name of the physical port (or ports) that this

 

Ethernet interface uses.

 

 

Zone

For the OPT interface, use this field to select the zone to which you want the

 

OPT interface to belong. For other Ethernet interfaces, this field is read-only and

 

displays the zone to which the Ethernet interface belongs.

 

 

MAC Address

This field is read-only. This is the MAC address that the Ethernet interface uses.

 

 

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

These IP address fields configure an IP address on the interface itself. If you

Assignment

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

This option is available for the WAN and OPT interfaces. Select this if this

Automatically

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 34 on page 575.

 

 

Use Fixed IP

This option is available for the WAN and OPT interfaces. The OPT, LAN, and

Address

DMZ interfaces always use static IP addresses. Select this if you want to specify

 

the IP address, subnet mask, and gateway manually. Enter the IP address,

 

subnet mask, and default gateway in the following fields.

 

 

IP Address

Enter the IP address for this interface. This option is enabled for the WAN and

 

OPT interfaces if you select Use Fixed IP Address.

 

 

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. This option is enabled for the WAN and OPT interfaces if you select

 

Use Fixed IP Address.

 

 

Gateway

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. This option is only

 

available for the WAN and OPT interfaces and only if you select Use Fixed IP

 

Address.

 

 

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.

Parameters

 

 

 

Egress

Enter the maximum amount of traffic, in kilobits per second, the ZyWALL can

Bandwidth

send through the interface to the network. Allowed values are 0 - 1048576. This

 

setting is used in WAN load balancing and bandwidth management.
