Network
Selection
Home network is the network to which you are originally subscribed.
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
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.
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
data budget
counters on
Select the date on which the ZyWALL resets the budget every month. If the date you
selected is not available in a month, such as 30th or 31st, the ZyWALL resets the
budget on the last day of the month.
Reset time and
data budget
counters
This button is available only when you enable budget control in this screen.
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.
Actions when
over budget
Specify the actions the ZyWALL takes when the time or data limit is exceeded.
Log Select None to not create a log, Log to create a log, or Log-alert to create an alert
log. If you select Log or Log-alert you can also select recurring every to have the
ZyWALL send a log or alert for this event periodically. Specify how often (from 1 to
65535 minutes) to send the log or alert.
New 3G
connection
Select Allow to permit new 3G connections or Disallow to drop/block new 3G
connections.
Current 3G
connection
Select Keep to maintain an existing 3G connection or Drop to disconnect it. You
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
% of time budget or
% of data budget
Specify the actions the ZyWALL takes when the specified percentage of time budget or
data limit is exceeded. Enter a number from 1 to 99 in the percentage fields. If you
change the value after you configure and enable budget control, the ZyWALL resets
the statistics.
