Chapter 8 LAN Setup

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.

Click Network > LAN > Client List to open the following screen. Use this screen to change 
your ZyXEL Device’s static DHCP settings.

Figure 57   LAN Client List

First DNS Server
Second DNS Server
Third DNS Server

Select Obtained From ISP if your ISP dynamically assigns DNS server 

information (and the ZyXEL Device's WAN IP address).
Select User-Defined if you have the IP address of a DNS server. Enter the DNS 

server's IP address in the field to the right. If you chose User-Defined, but leave 

the IP address set to 0.0.0.0, User-Defined changes to None after you click 

Apply. If you set a second choice to User-Defined, and enter the same IP 

address, the second User-Defined changes to None after you click Apply. 
Select DNS Relay to have the ZyXEL Device act as a DNS proxy only when the 

ISP uses IPCP DNS server extensions.

 

The ZyXEL Device's LAN IP address 

displays in the field to the right (read-only). The ZyXEL Device tells the DHCP 

clients on the LAN that the ZyXEL Device itself is the DNS server. When a 

computer on the LAN sends a DNS query to the ZyXEL Device, the ZyXEL 

Device forwards the query to the real DNS server learned through IPCP and 

relays the response back to the computer. You can only select DNS Relay for 

one of the three servers; if you select DNS Relay for a second or third DNS 

server, that choice changes to None after you click Apply. 
Select None if you do not want to configure DNS servers. You must have 

another DHCP sever on your LAN, or else the computers must have their DNS 

server addresses manually configured. If you do not configure a DNS server, 

you must know the IP address of a computer in order to access it.

Apply

Click Apply to save your changes back to the ZyXEL Device.

Click Reset to begin configuring this screen afresh.
