"

Use this screen to make the ZyXEL Device assign a specific IP address to a specific computer 
on the LAN. To access this screen, click Network > LAN > Static DHCP.

Pool Size

Enter the number of IP addresses to allocate. This number must be at least one 

and is limited by a subnet mask of 255.255.255.0 (regardless of the subnet the 

ZyXEL Device is in). For example, if the IP Pool Start Address is 10.10.10.10, 

the ZyXEL Device can allocate up to 10.10.10.254, or 245 IP addresses.

DNS Server

First DNS Server
Second DNS 

Server
Third DNS Server

Specify the IP addresses of a maximum of three DNS servers that the network can 

use. The ZyXEL Device provides these IP addresses to DHCP clients. You can 

specify these IP addresses

 

in the following ways.

Custom Defined - enter a static IP address
From ISP - provide the DNS servers provided by the ISP on the WAN port
DNS Relay - have the ZyXEL Device act as a DNS proxy. 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 ZyXEL Device's system DNS server 

(configured in the WAN > Advanced screen) 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.
None - do not use this DNS server. If you select None for all of the DNS servers, 

you must use IP addresses to configure the ZyXEL Device and to access the 

Internet.

Apply

Click this to save your changes and to apply them to the ZyXEL Device.

Reset

Click this to set every field in this screen to its last-saved value.
