Use DNS Redirection  
(Available in Wireless Routing Client and Gateway modes) 
 
When you enter a URL into your Internet browser, it requests for a name-
to-IP address translation from the Domain Name System (DNS) servers 
to locate the web server hosting the desired website. The DNS server 
searches its local cache for the answer, and if found, returns this 
cached IP address. Otherwise, it contacts other DNS servers until the 
query is answered.  
 
With DNS Redirection, DNS requests from the LAN clients are processed 
by the access point. It contacts the DNS server allocated by your ISP to 
resolve these DNS requests unless you have already specified a default 
DNS server in the access point LAN Setup. This default DNS server 
overrides the one defined in the TCP/IP settings of the LAN clients, 
allowing the access point to direct DNS requests from the LAN to a 
local or to a closer DNS server that it is aware of, thus improving the 
response time. 
 
DNS Redirection also provides more control to the network 
administrator. In the event that there is a change in DNS servers, he can 
simply indicate the actual DNS server IP address an the access point 
LAN Setup and enable DNS Redirection, without having to reconfigure 
the DNS settings of every LAN client.
