5.1
LAN Overview
The Configuration: LAN screen varies depending on the device type shown.
Local Area Network (LAN) is a shared communication system to which many computers are attached. Use the
LAN screens to configure a LAN DHCP server, manage IP addresses, and partition a physical network into
logical networks.
5.2
DHCP Setup
DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual clients to obtain
TCP/IP configuration at start-up from a server. You can configure the ZyXEL device as a DHCP server or
disable it. When configured as a server, the ZyXEL device provides the 44444444444444444444444/IP
configuration for the clients. If set to None, DHCP service will be disabled and you must have another DHCP
server on your LAN, or else the computer must be manually configured.
5.2.1 IP Pool Setup
The ZyXEL device is pre-configured with a pool of 32 IP addresses starting from 192.168.1.33 to 192.168.1.64.
This configuration leaves 31 IP addresses (excluding the ZyXEL device itself) in the lower range for other server
computers, for instance, servers for mail, FTP, TFTP, web, etc., that you may have.
5.2.2 DNS Servers
Use the LAN IP screen to configure the DNS server information that the ZyXEL device sends to the DHCP
client devices on the LAN.
5.3
LAN TCP/IP
The ZyXEL device has built-in DHCP server capability that assigns IP addresses and DNS servers to systems
that support DHCP client capability.
5.3.1 Factory LAN Defaults
The LAN parameters of the ZyXEL device are preset in the factory with the following values:
IP address of 192.168.1.1 with subnet mask of 255.255.255.0 (24 bits)
DHCP server enabled with 32 client IP addresses starting from 192.168.1.33.
These parameters should work for the majority of installations. If your ISP gives you explicit DNS server
address(es), read the embedded web configurator help regarding what fields need to be configured.
5.3.2 IP Address and Subnet Mask
Refer to the IP Address and Subnet Mask section in the Wizard Setup chapter for this information.
5.3.3 RIP Setup
RIP (Routing Information Protocol, RFC 1058 and RFC 1389) allows a router to exchange routing information
with other routers. RIP Direction controls the sending and receiving of RIP packets. When set to Both or Out
