Table 17   LAN IP

DHCP Server

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

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

server. Leave the DHCP Server check box selected unless your ISP instructs 

you to do otherwise. Clear it to disable the ZyAIR acting as a DHCP server. When 

configured as a server, the ZyAIR provides TCP/IP configuration for the clients. If 

not, DHCP service is disabled and you must have another DHCP server on your 

LAN, or else the computers must be manually configured. When set as a server, 

fill in the following four fields.

IP Pool Starting 

Address

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

Pool Size

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

DNS Servers Assigned by DHCP Server 
The ZyAIR passes a DNS (Domain Name System) server IP address (in the order you specify here) to 

the DHCP clients. The ZyAIR only passes this information to the LAN DHCP clients when you select the 

DHCP Server check box. When you clear the DHCP Server check box, DHCP service is disabled and 

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

addresses manually configured.
