Properties

 

 

 

Interface Type

Select to which type of network you will connect this interface. When

 

you select Internal or External the rest of the screen’s options

 

automatically adjust to correspond. The ZyWALL automatically adds

 

default route and SNAT settings for traffic it routes from internal

 

interfaces to external interfaces; for example LAN to WAN traffic.

 

Internal is for connecting to a local network. Other corresponding

 

configuration options: DHCP server and DHCP relay. The ZyWALL

 

automatically adds default SNAT settings for traffic flowing from this

 

interface to an external interface.

 

External is for connecting to an external network (like the Internet).

 

The ZyWALL automatically adds this interface to the default WAN

 

trunk.

 

For General, the rest of the screen’s options do not automatically

 

adjust and you must manually configure a policy route to add routing

 

and SNAT settings for the interface.

 

 

Interface

Specify a name for the interface. It can use alphanumeric characters,

Name

hyphens, and underscores, and it can be up to 11 characters long.

 

 

Port

This is the name of the Ethernet interface’s physical port.

 

 

Zone

Select the zone to which this interface is to belong. You use zones to

 

apply security settings such as firewall, IDP, remote management,

 

anti-virus, and application patrol.

 

 

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.

Assignment

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

This option appears when Interface Properties is External or

Automatically

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.
