DESCRIPTION
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.
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.
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
31th, the ZyWALL resets the budget on the last day of the month.
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.
Specify the actions the ZyWALL takes when the time or data limit is
exceeded.
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.
Select Allow to permit new 3G connections or Disallow to drop/block
new 3G connections.
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.
