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 Fa ctory Default
to select the factory assigned default MAC Address.
Otherwise, click Clone t he com puter's MAC address - I P Addr e ss 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.
Figure 50 Multicast Example
In the multicast example above, systems A and D comprise one multicast group. In multicasting,
the server only needs to send one data stream and this is delivered to systems A and D.
