DESCRIPTION

Login Name

Type the login name assigned by your ISP.

 

 

Password

Type the password assigned by your ISP.

 

 

Retype to Confirm

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

 

 

Authentication

Use the drop-down list box to select an authentication protocol for outgoing calls.

Type

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.

 

 

Primary/ Secondary

Type the first (primary) phone number from the ISP for this remote node. If the

Phone Number

Primary Phone number is busy or does not answer, your ZyWALL dials the

 

Secondary Phone number if available. Some areas require dialing the pound

 

sign # before the phone number for local calls. Include a # symbol at the

 

beginning of the phone numbers as required.

 

 

Dial Backup Port

Use the drop-down list box to select the speed of the connection between the

Speed

Dial Backup port and the external device. Available speeds are: 9600, 19200,

 

38400, 57600, 115200 or 230400 bps.

 

 

AT Command Initial

Type the AT command string to initialize the WAN device. Consult the manual of

String

your WAN device connected to your Dial Backup port for specific AT commands.

 

 

Advanced Modem

Click Edit to display the Advanced Setup screen and edit the details of your dial

Setup

backup setup.

 

 

TCP/IP Options

 

 

 

Get IP Address

Type the login name assigned by your ISP for this remote node.

Automatically from

 

Remote Server

 

 

 

Used Fixed IP

Select this check box if your ISP assigned you a fixed IP address, then enter the

Address

IP address in the following field.

 

 

My WAN IP

Leave the field set to 0.0.0.0 (default) to have the ISP or other remote router

Address

dynamically (automatically) assign your WAN IP address if you do not know it.

 

Type your WAN IP address here if you know it (static). This is the address

 

assigned to your local ZyWALL, not the remote router.

 

 

Enable NAT

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

(Network Address

address used within one network to a different IP address known within another

Translation)

network.

 

Select the check box to enable NAT. Clear the check box to disable NAT so the

 

ZyWALL does not perform any NAT mapping for the dial backup connection.

 

 

Enable RIP

Select this check box to turn on RIP (Routing Information Protocol), which allows

 

a router to exchange routing information with other routers.

 

 

RIP Version

The RIP Version field controls the format and the broadcasting method of the

 

RIP packets that the ZyWALL sends (it recognizes both formats when receiving).

 

Choose RIP-1,RIP-2B or RIP-2M.

 

RIP-1is universally supported; but RIP-2carries more information. RIP-1 is

 

probably adequate for most networks, unless you have an unusual network

 

topology. Both RIP-2Band RIP-2Msends the routing data in RIP-2 format; the

 

difference being that RIP-2B uses subnet broadcasting while RIP-2M uses

 

multicasting. Multicasting can reduce the load on non-router machines since they

 

generally do not listen to the RIP multicast address and so will not receive the

 

RIP packets. However, if one router uses multicasting, then all routers on your

 

network must use multicasting, also.
