ZyWALL 5/35/70 Series User's Guide
DESCRIPTION
This field displays with a GSM or HSDPA 3G card. A PIN (Personal Identification
Number) code is a key to a 3G card. Without the PIN code, you cannot use the 3G
card.
Enter the 4-digit PIN code (0000 for example) provided by your ISP. If you enter the
PIN code incorrectly, the 3G card may be blocked by your ISP and you cannot use
the account to access the Internet.
If your ISP disabled PIN code authentication, enter an arbitrary number.
Enter the phone number (dial string) used to dial up a connection to your service
provider's base station. Your ISP should provide the phone number.
For example, *99# is the dial string to establish a GPRS or 3G connection in
Taiwan.
Select Nailed-Up if you do not want the connection to time out.
This value specifies the time in seconds that elapses before the ZyWALL
automatically disconnects from the ISP.
Select this option If your ISP did not assign you a fixed IP address. This is the
default selection.
Select this option If the ISP assigned a fixed IP address.
Enter your WAN IP address in this field if you selected Use Fixed IP Address.
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
Select this check box to turn on IGMP (Internet Group Management Protocol).
IGMP is a network-layer protocol used to establish membership in a Multicast
group - it is not used to carry user data.
Choose None (default), IGMP-V1 or IGMP-V2. IGMP (Internet Group Management
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 inter-operability between
IGMP version 2 and version 1, please see sections 4 and 5 of RFC 2236.
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.
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.
