alphanumeric and ()+/:=?!*#@$_%- characters, and it can be up to 60

 

characters long.

Connectivity

 

 

 

Nailed-Up

Select this if the connection should always be up. Clear this to have the ZyWALL

 

to establish the connection only when there is traffic. You might not nail up the

 

connection if there is little traffic through the interface or if it costs money to keep

 

the connection available.

 

 

Idle timeout

This value specifies the time in seconds (0~360) that elapses before the ZyWALL

 

automatically disconnects from the ISP’s server. Zero disables the idle timeout.

select the profile (use Profile 1 unless your ISP instructed you to do otherwise).

APN

This field is read-only if you selected Device in the profile selection. Select

 

Custom in the profile selection to be able to manually input the APN (Access

 

Point Name) provided by your service provider. This field applies with a GSM or

 

HSDPA 3G card. Enter the APN from your service provider. Connections with

 

different APNs may provide different services (such as Internet access or MMS

 

(Multi-Media Messaging Service)) and charge method.

 

You can enter up to 63 ASCII printable characters. Spaces are allowed.

 

 

Dial String

Enter the dial string if your ISP provides a string, which would include the APN, to

This field is available only when you insert a GSM 3G card.

 

 

Authentication

The ZyWALL supports PAP (Password Authentication Protocol) and CHAP

Type

(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:

 

None: No authentication for outgoing calls.

 

CHAP - Your ZyWALL accepts CHAP requests only.

 

PAP - Your ZyWALL accepts PAP requests only.
