Authentication 
Method
The ZyXEL Device 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 ZyXEL Device accepts either CHAP or PAP when requested by this remote 
node.
PAP: Your ZyXEL Device accepts PAP only. 
CHAP: Your ZyXEL Device accepts CHAP only.
MSCHAP: Your ZyXEL Device accepts MSCHAP only. MS-CHAP is the Microsoft version 
of the CHAP.
Use Static IP Address A static IP 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 do not have a dynamic IP address.
IP Address
Enter the static IP address provided by your ISP. You will only see this field if you
