5.1.3  DHCP Server Settings

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 TCP/IP configuration for the DHCP client. If DHCP service is disabled, you must 
have another DHCP server on your LAN, or else the computer must be manually configured. 

To configure DHCP settings on the ZyXEL Device, set the 

DHCP SERVER SETTINGS 

fields in the 

LAN

 screen. You can also view the list of DHCP client computers in this screen. 

Figure 39   

Basic: LAN: DHCP Server Settings 

The following table describes the labels in this screen.

DESCRIPTION

ENABLE

Enable DHCP 

Server 

DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows 

individual clients (workstations) to obtain TCP/IP configuration at startup from a 

server. 
Select

 

this option to set the ZyXEL Device to assign network information (IP 

address, DNS information etc.) to an Ethernet device connected to the 

LAN 

ports.

Clear this check box to stop the ZyXEL Device from acting as a DHCP server. you 

must have another DHCP server on your LAN, or else the computer must be 

manually configured. 

DHCP Address 

Range

The ZyXEL Device is pre-configured to provide IP addresses (ranging from 

192.168.1.100 to 192.168.1.199) to DHCP clients. This configuration leaves some 

IP addresses (excluding the ZyXEL Device itself) in the lower and upper ranges for 

other server computers, for instance, servers for mail, FTP, TFTP, web, etc., that 

you may have.
Specify the starting and end IP address for the DHCP clients.
