Authentication
Method
The P-870HN-51D supports PAP (Password Authentication Protocol)
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
Timeout
Specify an idle time-out when you select Dial on Demand. The
default setting is 0, which means the Internet session will not timeout.
Use Static IPv4
Address
A static IPv4 address is a fixed IP that your ISP gives you. A dynamic
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
Debug Mode
Select this option to display PPP debugging messages on the console.
