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.

Enable NAT

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

(Network Address

Translation)

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 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.
