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.

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.

field if you select Use Static IP Address
Routing Feature

IGMP Proxy
Enable 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.

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.
