Chapter 6 LAN Screens
224.0.0.0 is not assigned to any group and is used by IP multicast computers. 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 in the web configurator (LAN;
WAN). Select None to disable IP multicasting on these interfaces.

6.6 WINS

WINS (Windows Internet Naming Service) is a Windows implementation of NetBIOS Name
Server (NBNS) on Windows. It keeps track of NetBIOS computer names. It stores a mapping
table of your network's computer names and IP addresses. The table is dynamically updated
for IP addresses assigned by DHCP. This helps reduce broadcast traffic since computers can
query the server instead of broadcasting a request for a computer name's IP address. In this
way WINS is similar to DNS, although WINS does not use a hierarchy (unlike DNS). A
network can have more than one WINS server. Samba can also serve as a WINS server.

6.7 LAN

Click NETWORK > LAN to open the LAN screen. Use this screen to configure the
ZyWALL's IP address and other LAN TCP/IP settings as well as the built-in DHCP server
capability that assigns IP addresses and DNS servers to systems that support DHCP client
capability.
