ZyWALL 10 Internet Security Gateway
The address 224.0.0.1 is used for query messages and is assigned to the permanent group of all IP hosts
(including gateways). All hosts must join the 224.0.0.1 group in order to participate in IGMP. The address
224.0.0.2 is assigned to the multicast routers group.
The ZyWALL supports both IGMP version 1 (IGMP-v1) and IGMP version 2 (IGMP-v2). At start up, the
ZyWALL queries all directly connected networks to gather group membership. After that, the ZyWALL
periodically updates this information. IP Multicasting can be enabled/disabled on the ZyWALL LAN and/or
WAN interfaces using menus 3.2 (LAN) and 11.3 (WAN). Select None to disable IP Multicasting on these
interfaces.

3.1.7 IP Alias

IP Alias allows you to partition a physical network into different logical networks over the same Ethernet
interface. The ZyWALL supports three logical LAN interfaces via its single physical Ethernet interface with
the ZyWALL itself as the gateway for each LAN network.
