WAN MAC Address
The MAC address screen allows users to configure the WAN port's MAC address by
either using the factory default or cloning the MAC address from a computer on
your LAN. Choose
Factory Default
to select the factory assigned default MAC
Address.
Otherwise, click
Clone the computer's MAC address - IP Address
and enter
the IP address of the computer on the LAN whose MAC you are cloning. Once it is
successfully configured, the address will be copied to configuration file. It is
recommended that you clone the MAC address prior to hooking up the WAN Port.
Multicast
Traditionally, IP packets are transmitted in one of either two ways - Unicast (1
sender - 1 recipient) or Broadcast (1 sender - everybody on the network).
Multicast delivers IP packets to a group of hosts on the network - not everybody
and not just 1.

Multicast Example
In the multicast example above, systems A and B comprise one multicast group.
In multicasting, the server only needs to send one data stream and this is
delivered to systems A and B.
IGMP (Internet Group Multicast Protocol) is a network-layer protocol used to
establish membership in a multicast group - it is not used to carry user data. The
NBG4115 supports both IGMP version 1 (
IGMP-v1
) and IGMP version 2 (
IGMP-
v2
).
At start up, the NBG4115 queries all directly connected networks to gather group
membership. After that, the NBG4115 periodically updates this information. IP
multicasting can be enabled/disabled on the NBG4115 LAN and/or WAN interfaces
in the Web Configurator (
LAN
;
WAN
). Select
None
to disable IP multicasting on
these interfaces.
NetBIOS over TCP/IP
NetBIOS (Network Basic Input/Output System) are TCP or UDP broadcast packets
that enable a computer to connect to and communicate with a LAN. For some dial-
