When you enter a URL in your Internet browser, the browser requests for 

a name-to-IP address translation from the Domain Name System (DNS) 
servers to be able to locate the web server hosting the website you 
want to access. 
 
The DNS server, in turn, looks for the answer in its local cache and if an 

appropriate entry is found, sends back this cached IP address to the 

browser. Otherwise, it would have to contact other DNS servers until the 
query can be resolved.  
 

When you enable the DNS Redirection feature, the router will process 
DNS requests from the LAN clients. Unless in the router's LAN Setup you 
have already assigned a specific DNS server that should always be 
used, the router would contact the DNS server allocated by your ISP to 
resolve DNS requests. 
 
When  DNS Redirection is enabled, the DNS server used by the router 
would override the one defined in the TCP/IP settings of the LAN clients. 
This allows the router to direct DNS requests from the LAN to a local or 
to a closer DNS server it knows of, thus improving response time.  
 
The DNS Redirection feature also provides better control to the network 
administrator. In case of a change in DNS servers, the latter can just 
indicate the IP address of the actual DNS server in the router's LAN 
Setup and enable DNS Redirection, without having to re-configure the 
DNS settings of each LAN client.
