DESCRIPTION

 

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:

 

 

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-Upif 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 PPPoE server.

Advanced Setup

 

 

 

 

 

Enable NAT

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

 

(Network

address used within one network (for example a private IP address used in a local

 

Address

network) to a different IP address known within another network (for example a

 

Translation)

public IP address used on the Internet).

 

 

Select this checkbox to enable NAT.

 

 

For more information about NAT see Chapter 17 on page 385.

 

 

 

 

RIP Direction

RIP (Routing Information Protocol) allows a router to exchange routing information

 

 

with other routers. The RIP Direction field controls the sending and receiving of

 

 

RIP packets.

 

 

Choose Both, None, In Only or Out Only.

 

 

When set to Both or Out Only, the ZyWALL will broadcast its routing table

 

 

periodically.

 

 

When set to Both or In Only, the ZyWALL will incorporate RIP information that it

 

 

receives.

 

 

When set to None, the ZyWALL will not send any RIP packets and will ignore any

 

 

RIP packets received.

 

 

By default, RIP Direction is set to Both.

 

 

 

 

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. By default, the RIP Version field is set to RIP-1.
