FIELD

DESCRIPTION

 

 

Size of Client IP

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

Pool

 

First DNS Server

The ZyAIR passes a DNS (Domain Name System) server IP address (in the order

Second DNS

you specify here) to the DHCP clients.

Select From ISP if your ISP dynamically assigns DNS server information (and the

Server

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

Third DNS Server

DNS server IP address that the ISP assigns.

 

Select User-Definedif 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-Definedchanges 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-Definedchanges to None after you save your changes.

 

Select DNS Relay to have the ZyAIR act as a DNS proxy. The ZyAIR's LAN IP

 

address displays in the IP Address field below (read-only). The ZyAIR tells the

 

DHCP clients on the LAN that the ZyAIR itself is the DNS server. When a computer

 

on the LAN sends a DNS query to the ZyAIR, the ZyAIR forwards the query to the

 

ZyAIR'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

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

Address

remote DHCP server here.

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