Advanced Setup
Enable NAT
(Network
Address
Translation)
Network Address Translation (NAT) allows the translation of an Internet protocol
address used within one network (for example a private IP address used in a local
network) to a different IP address known within another network (for example a
public IP address used on the Internet).
Select this checkbox to enable NAT.
For more information about NAT see
Enable Multicast
Select this check box to turn on IGMP (Internet Group Multicast Protocol). IGMP is
a network-layer protocol used to establish membership in a Multicast group - it is
not used to carry user data.
Multicast Version
Choose
None
(default),
IGMP-V1
or
IGMP-V2
. IGMP (Internet Group Multicast
Protocol) is a session-layer protocol used to establish membership in a Multicast
group – it is not used to carry user data. IGMP version 2 (RFC 2236) is an
improvement over version 1 (RFC 1112) but IGMP version 1 is still in wide use. If
you would like to read more detailed information about interoperability between
IGMP version 2 and version 1, please see sections 4 and 5 of RFC 2236.
Enable Budget
Control
Select this check box to set a monthly limit for the user account of the installed 3G
card. You must insert a 3G card before you enable budget control on the ZyWALL.
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 check box 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 check box and specify how much downstream and/or upstream data (in
Mbytes) 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 31th, the ZyWALL resets
the budget on the last day of the month.
