DESCRIPTION
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.
CHAP: Your ZyXEL Device accepts CHAP only.
PAP: Your ZyXEL Device accepts PAP only.
MSCHAP: Your ZyXEL Device accepts MSCHAP only. MS-CHAP is the
Microsoft version of the CHAP.
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 want to get a dynamic IP
address from the ISP.
Enter the static IP address provided by your ISP.
In addition to the ZyXEL Device's built-in PPPoE client, you can enable
PPPoE pass through to allow up to ten hosts on the LAN to use PPPoE
client software on their computers to connect to the ISP via the ZyXEL
Device. Each host can have a separate account and a public WAN IP
address.
PPPoE pass through is an alternative to NAT for application where NAT
is not appropriate.
Disable PPPoE pass through if you do not need to allow hosts on the
LAN to use PPPoE client software on their computers to connect to the
ISP.
Select this option to activate NAT on this connection.
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.
Select this option to have the ZyXEL Device use the WAN interface of
this connection as the system default gateway.
The section is not available when you select Bridge in the WAN
Service Type field.
Select this to have the ZyXEL Device get the DNS server addresses
from the ISP automatically.
Select this to have the ZyXEL Device use the DNS server addresses
you configure manually.
