Advanced Setup

 

 

 

Enable NAT

Network Address Translation (NAT) allows the translation of an Internet protocol

(Network

address used within one network (for example a private IP address used in a local

Address

network) to a different IP address known within another network (for example a

Translation)

public IP address used on the Internet).

 

Select this checkbox to enable NAT.

 

For more information about NAT see Chapter 17 on page 385.

 

 

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-V1or 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

Select this check box to set a monthly limit for the user account of the installed 3G

Control

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

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

data budget

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

counters on

the budget on the last day of the month.
