Interface Properties

 

 

 

Interface Name

Select a name for the interface.

 

 

Zone

Select the zone to which you want the cellular interface to belong. The zone

 

determines the security settings the ZyWALL uses for the interface.

 

 

Extension Slot

This is the USB slot that you are configuring for use with a 3G card.

 

 

Connected

This displays the manufacturer and model name of your 3G card if you inserted one in

Device

the ZyWALL. Otherwise, it displays none.

 

 

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.

Connectivity

 

 

 

Nailed-Up

Select this if the connection should always be up. Clear this to have the ZyWALL to

 

establish the connection only when there is traffic. You might not nail up the

 

connection if there is little traffic through the interface or if it costs money to keep the

 

connection available.

 

 

Idle timeout

This value specifies the time in seconds (0~360) that elapses before the ZyWALL

 

automatically disconnects from the ISP’s server. Zero disables the idle timeout.

 

 

ISP Settings

 

 

 

Profile Selection

Select Device to use one of the 3G device’s profiles of device settings. Then select the

 

profile (use Profile 1 unless your ISP instructed you to do otherwise).

 

Select Custom to configure your device settings yourself.

 

 

APN

This field is read-only if you selected Device in the profile selection. Select Custom in

 

the profile selection to be able to manually input the APN (Access Point Name)

 

provided by your service provider. This field applies with a GSM or HSDPA 3G card.

 

Enter the APN from your service provider. Connections with different APNs may provide

 

different services (such as Internet access or MMS (Multi-Media Messaging Service))

 

and charge method.

 

You can enter up to 63 ASCII printable characters. Spaces are allowed.

 

 

Dial String

Enter the dial string if your ISP provides a string, which would include the APN, to

 

initialize the 3G card.

 

You can enter up to 63 ASCII printable characters. Spaces are allowed.

 

This field is available only when you insert a GSM 3G card.

 

 

Authentication

The ZyWALL supports PAP (Password Authentication Protocol) and CHAP (Challenge

Type

Handshake Authentication Protocol). CHAP is more secure than PAP; however, PAP is

 

readily available on more platforms.

 

Use the drop-down list box to select an authentication protocol for outgoing calls.

 

Options are:

 

None: No authentication for outgoing calls.

 

CHAP - Your ZyWALL accepts CHAP requests only.

 

PAP - Your ZyWALL accepts PAP requests only.
