Chapter 5 LAN Setup

The following table describes the labels in this screen.

This table allows you to assign IP addresses on the LAN to specific individual computers 
based on their MAC Addresses. 

Every Ethernet device has a unique MAC (Media Access Control) address. The MAC address 
is assigned at the factory and consists of six pairs of hexadecimal characters, for example, 
00:A0:C5:00:00:02.

To change your ZyXEL Device’s static DHCP settings, click Network > LAN > Client List. 
The screen appears as shown.

Table 32   DHCP Setup

DHCP Setup

DHCP

Select what type of DHCP services the ZyXEL Device provides to the network. 

Choices are:
None - the ZyXEL Device does not provide any DHCP services. There is 

already a DHCP server on the network.
DHCP Relay - the ZyXEL Device routes DHCP requests to the DHCP server. 

There may be a DHCP server on another network.
DHCP Server - the ZyXEL Device assigns IP addresses and provides subnet 

mask, gateway, and DNS server information to the network. The ZyXEL Device 

is the DHCP server for the network.

IP Pool Starting 

Address

This field is enabled if the ZyXEL Device is a DHCP Server. Enter the first of the 

contiguous addresses in the IP address pool.

Pool Size

This field is enabled if the ZyXEL Device is a DHCP Server. Enter the size of, or 

the number of addresses in, the IP address pool.

Remote DHCP 

Server

This field is enabled if the ZyXEL Device is a DHCP Relay. Enter the IP address 

of the DHCP server to which the ZyXEL Device should route requests.

DNS Server

DNS Servers 

Assigned by DHCP 

Server

The ZyXEL Device passes a DNS (Domain Name System) server IP address to 

the DHCP clients. 

Primary DNS Server
Secondary DNS 

Server

This field is not available when you set DHCP to Relay.
Enter the IP addresses of the DNS servers. The DNS servers are passed to the 

DHCP clients along with the IP address and the subnet mask.
If the fields are left as 0.0.0.0, the ZyXEL Device acts as a DNS proxy and 

forwards the DHCP client’s DNS query to the real DNS server learned through 

IPCP and relays the response back to the computer.
