Get 

Automatically 

Select this option If your ISP did not assign you a fixed IP address. 
This is the default selection. 

Use Fixed IP 

Address

Select this option If the ISP assigned a fixed IP 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 

Selection

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

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