Address

 

 

 

IP Address

Enter the cellular interface’s WAN IP address in this field if you

 

selected 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.

 

 

Device Settings

 

 

 

Device

Select the 3G card to use with this entry or select auto to have the

Selection

ZyWALL automatically detect the type of card.

 

 

Band Selection

This field appears if you selected a 3G device that allows you to select

 

the type of network to use. Select the type of 3G service for your 3G

 

connection. If you are unsure what to select, check with your 3G

 

service provider to find the 3G service available to you in your region.

 

Select auto to have the card connect to an available network. Choose

 

this option if you do not know what networks are available.

 

You may want to manually specify the type of network to use if you

 

are charged differently for different types of network or you only have

 

one type of network available to you.

 

Select GPRS / EDGE (GSM) only to have this interface only use a

 

2.5G or 2.75G network (respectively). If you only have a GSM

 

network available to you, you may want to select this so the ZyWALL

 

does not spend time looking for a WCDMA network.

 

Select UMTS / HSDPA (WCDMA) only to have this interface only

 

use a 3G or 3.5G network (respectively). You may want to do this if

 

you want to make sure the interface does not use the GSM network.

 

 

Enable Budget

Select this to set a monthly limit for the user account of the installed

Control

3G card. You can set a limit on the total traffic and/or call time. The

 

ZyWALL takes the actions you specified when a limit is exceeded

 

during the month.

 

Note: The ZyWALL automatically uses whichever service

 

provider’s 3G network to which it can connect. This could

 

result in higher fees or roaming charges if it uses other

 

service providers’ networks, especially if your 3G provider

 

has poor coverage in your area or you frequently move

 

your ZyWALL to different locations.

 

 

Time Budget

Select this and specify the amount of time (in hours) that the 3G

 

connection can be used within one month. If you change the value

 

after you configure and enable budget control, the ZyWALL resets the

 

statistics.
