DESCRIPTION

Authentication

The P-870HN-51D supports PAP (Password Authentication Protocol)

Method

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:

 

AUTO - Your P-870HN-51D accepts either CHAP or PAP when

 

requested by this remote node.

 

CHAP - Your P-870HN-51D accepts CHAP only.

 

PAP - Your P-870HN-51D accepts PAP only.

 

MSCHAP - Your P-870HN-51D accepts MSCHAP only. MS-CHAP is the

 

Microsoft version of the CHAP.

 

 

Enable NAT

Select this option to enable NAT on the P-870HN-51D. You can also

 

select the NAT Type you want the P-870HN-51D to implement. The

 

choices are as follows:

 

Symmetric NAT (default) - Symmetric NAT maps requests from

 

the same private IP address and port to a different public source IP

 

address and/or port depending on the packet's destination IP

 

address.

 

Port Restricted Cone NAT - Restricted cone NAT maps all

 

requests from the same private IP address and port to the same

 

public source IP address and port.

 

Restricted Cone NAT - Restricted cone NAT maps all requests

 

from the same private IP address to the same public source IP

 

address.

 

Full Cone NAT - In full cone NAT, all requests from the same

 

private IP address and port are mapped to the same public source

 

IP address and port. Someone on the Internet only needs to know

 

the mapping scheme in order to send packets to a device behind

 

the NAT router.

 

 

Dial on Demand

Select this check box when you do not want the connection up all the

 

time and specify an idle time-out in the Inactivity Timeout field.

 

 

Inactivity

Specify an idle time-out when you select Dial on Demand. The

Timeout

default setting is 0, which means the Internet session will not timeout.

 

 

Use Static IPv4

A static IPv4 address is a fixed IP that your ISP gives you. A dynamic

Address

IP address is not fixed; the ISP assigns you a different one each time

 

you connect to the Internet. Select this if you want to use a static IP

 

address instead of a dynamic IP address.

 

 

IPv4 Address

Enter the static IP address provided by your ISP.

 

 

Enable PPP
