DESCRIPTION

 

 

Network

Home network is the network to which you are originally subscribed.

 

 

Selection

Select Home to have the 3G device connect only to the home network. If the home

 

 

 

 

 

 

network is down, the ZyWALL’s 3G Internet connection is also unavailable.

 

 

 

Select Auto (Default) to allow the 3G device to connect to a network to which you are

 

 

 

not subscribed when necessary, for example when the home network is down or

 

 

 

another 3G base station's signal is stronger. This is recommended if you need

 

 

 

continuous Internet connectivity. If you select this, you may be charged using the rate

 

 

 

of a different network.

 

 

 

 

 

 

Budget Setup

 

 

 

 

 

 

 

Enable Budget

Select this to set a monthly limit for the user account of the installed 3G card. You can

 

 

Control

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.

 

 

 

 

 

 

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.

 

 

 

 

 

 

Data Budget

Select this and specify how much downstream and/or upstream data (in Mega bytes)

 

 

 

can be transmitted via the 3G connection within one month.

 

 

 

Select Download to set a limit on the downstream traffic (from the ISP to the

 

 

 

ZyWALL).

 

 

 

Select Upload to set a limit on the upstream traffic (from the ZyWALL to the ISP).

 

 

 

Select Download/Upload to set a limit on the total traffic in both directions.

 

 

 

If you change the value after you configure and enable budget control, the ZyWALL

 

 

 

resets the statistics.

 

 

 

 

 

 

Reset time and

Select the date on which the ZyWALL resets the budget every month. If the date you

 

 

data budget

selected is not available in a month, such as 30th or 31st, the ZyWALL resets the

 

 

counters on

budget on the last day of the month.

counters

Click this button to reset the time and data budgets immediately. The count starts over

 

 

 

with the 3G connection’s full configured monthly time and data budgets. This does not

 

 

 

affect the normal monthly budget restart; so if you configured the time and data

 

 

 

budget counters to reset on the second day of the month and you use this button on

 

 

 

the first, the time and data budget counters will still reset on the second.

Current 3G

Select Keep to maintain an existing 3G connection or Drop to disconnect it. You

 

 

connection

cannot set New 3G connection to Allow and Current 3G connection to Drop at

 

 

 

the same time.

 

 

 

If you set New 3G connection to Disallow and Current 3G connection to Keep,

 

 

 

the ZyWALL allows you to transmit data using the current connection, but you cannot

 

 

 

build a new connection if the existing connection is disconnected.

 

 

 

 

 

 

Actions when over

Specify the actions the ZyWALL takes when the specified percentage of time budget or

 

 

% of time budget or

data limit is exceeded. Enter a number from 1 to 99 in the percentage fields. If you
