8.8 WAN Multicast

Multicast allows packets to be transmitted to multiple hosts. Multicast is an alternative to
unicast packets (packets sent to one computer) and broadcast packets (packets sent to every
computer).
IGMP (Internet Group Management Protocol) is a network-layer protocol used to establish
membership in a multicast group - it is not used to carry user data.
When you have multicast enabled, the ZyXEL Device queries all directly connected networks
when it starts up to gather group membership. After that, the ZyXEL Device periodically
updates this information.

DESCRIPTION
Set how long the Internet connection can be idle before ZyXEL Device disconnects
it. This only applies if you set the Internet connection to not be always on.
Type the IP address of the PPTP server.
Enter your WAN IP address in this field. You assign this IP address to the WAN
interface temporarily to initiate the PPTP negotiation.
Enter the IP subnet mask in this field.
The MAC address section allows users to configure the WAN port's MAC address
by either using the ZyXEL Device's MAC address, cloning a computer's IP address,
or manually entering a MAC address.
Select this option to use the factory assigned default MAC address.
Select this option and enter the IP address of the computer on the LAN that is used
for Internet access. Enter the IP address in dotted decimal notation, for example,
192.168.1.25. Once it is successfully configured, the address will be copied to the
ZyXEL Device's configuration file. It will not change unless you change the setting
or upload a different configuration file. This MAC address also displays in the
Status screen.
Select this option and enter the MAC address of the computer on the LAN that is
used for Internet access. Enter the MAC address using colons, for example,
00:A0:C5:00:00:02. Once it is successfully configured, the address will be copied to
the ZyXEL Device's configuration file. It will not change unless you change the
setting or upload a different configuration file. This MAC address also displays in
the Status screen.
Click OK to save your changes back to the ZyXEL Device.
Click Cancel to begin configuring this screen afresh.
