DESCRIPTION
The ZyXEL Device 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 ZyXEL Device accepts either CHAP or PAP when requested by
the ISP.
CHAP - Your ZyXEL Device accepts CHAP only.
PAP - Your ZyXEL Device accepts PAP only.
None - Your ZyXEL Device does not send your user name and password for
authentication. The user name and password fields are grayed out. Select this
option if your ISP did not give you a user name and password.
Type the user name (of up to 31 ASCII printable characters) given to you by your
service provider.
Type the password (of up to 31 ASCII printable characters) associated with the
user name above.
Type your password again to make sure that you have entered is correctly.
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 PIN code (four to eight digits, 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.
This field is available only when you insert a GSM 3G card.
Check the HOME screen to see if you have entered the correct PIN.
Enter the phone number (dial string) used to dial up a connection to your service
provider's base station. Your ISP should provide the dial string.
By default, *99# is the dial string for GSM-based networks and #777 is the dial
string for CDMA-based networks.
Select Nailed-Up if you do not want the connection to time out.
This specifies the time (from 0 to 9999) in seconds that elapses before the ZyXEL
Device 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 Chapter 12 on page 225.
