Chapter 22 LAN Setup

249

Use the instructions in the following table to configure TCP/IP parameters for the LAN port.

Table 88   DHCP Ethernet Setup Fields

DHCP

This field enables/disables the DHCP server.
If set to Server, your ZyXEL device will act as a DHCP server.
If set to None, the DHCP server will be disabled.
If set to Relay the ZyXEL device acts as a surrogate DHCP server and relays 

requests and responses between the remote server and the clients.
When set to Server, the following items need to be set:

Client IP Pools

Starting Address

This field specifies the first of the contiguous addresses in the IP address pool.

Size of Client IP 

Pool

This field specifies the size, or count of the IP address pool.

First DNS Server

Second DNS 
Server

Third DNS Server

The ZyXEL device passes a DNS (Domain Name System) server IP address (in the 

order you specify here) to the DHCP clients. 
Select From ISP if your ISP dynamically assigns DNS server information (and the 

ZyXEL device's WAN IP address). The IP Address field below displays the (read-

only) DNS server IP address that the ISP assigns. 
Select User-Defined if you have the IP address of a DNS server. Enter the DNS 

server's IP address in the IP Address field below. If you chose User-Defined, but 

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

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

address, the second User-Defined changes to None after you save your changes.
Select DNS Relay to have the ZyXEL device act as a DNS proxy. The ZyXEL 

device's LAN IP address displays in the IP Address field below (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 ZyXEL device's system DNS 

server (configured in menu 1) 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 save your 

changes.
Select None if you do not want to configure DNS servers. If you do not configure a 

DNS server, you must know the IP address of a machine in order to access it.

DHCP Server 

Address

If Relay is selected in the DHCP field above, then type the IP address of the actual, 

remote DHCP server here.
