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

address.

field if you select Use Static IP Address
Routing Feature

Internet Group Multicast Protocol (IGMP) is a network-layer protocol
used to establish membership in a Multicast group - it is not used to
carry user data.
Select this option to have the ZyXEL Device act as an IGMP proxy on
this connection. This allows the ZyXEL Device to get subscribing
information and maintain a joined member list for each multicast
group. It can reduce multicast traffic significantly.
