Chapter 8 LAN Setup

DHCP

A DHCP (Dynamic Host Configuration Protocol) server can assign your ZyXEL Device an IP address, subnet mask, DNS and other routing information when it's turned on.

RIP

RIP (Routing Information Protocol) allows a router to exchange routing information with other routers.

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.

IGMP

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. There are three versions of IGMP. IGMP version 2 is an improvement over version 1, but IGMP version 1 is still in wide use. IGMP version 3 supports source filtering, reporting or ignoring traffic from specific source address to a particular host on the network.

DNS

DNS (Domain Name System) is for mapping a domain name to its corresponding IP address and vice versa. The DNS server is extremely important because without it, you must know the IP address of a networking device before you can access it.

See Section 8.3 on page 71 for technical background information on LANs.

8.2 The LAN Screen

Use this screen to configure your LAN settings. Click Interface Setup > LAN to display the following screen.

Follow these steps to configure your LAN settings.

1Enter an IP address into the IP Address field. The IP address must be in dotted decimal notation. This will become the IP address of your ZyXEL Device.

2Enter the IP subnet mask into the IP Subnet Mask field. Unless instructed otherwise it is best to leave this alone, the configurator will automatically compute a subnet mask based upon the IP address you entered.

3Click SAVE to save your settings.
