Confirm

Type your password again to make sure that you have entered is correctly.

PIN Code

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.

Phone 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.

Authentication

Type

The ZyWALL supports PAP (Password Authentication Protocol) and CHAP

(Challenge Handshake Authentication Protocol). CHAP is more secure than PAP;

however, PAP is readily available on more platforms.
Use the drop-down list box to select an authentication protocol for outgoing calls.

Options are:
CHAP/PAP - Your ZyWALL accepts either CHAP or PAP when requested by this

remote node.
CHAP - Your ZyWALL accepts CHAP only.
PAP - Your ZyWALL accepts PAP only.

Nailed-Up Select

Nailed-Up if you do not want the connection to time out.

Idle Timeout

This value specifies the time in seconds that elapses before the ZyWALL

automatically disconnects from the ISP.

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

Chapter 17 on page 329

.

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.
