(only supported by Wireless Routing Client and Gateway)
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, DNS requests from the LAN
clients will be processed by Access point. Unless in the access point’s LAN Setup
you have already assigned a specific DNS server that should always be used,
the access point would contact the DNS server allocated by your ISP to resolve
DNS requests.
When DNS Redirection is enabled, the DNS server used by the access point
would override the one defined in the TCP/IP settings of the LAN clients. This
allows the access point 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 access point's LAN Setup and
enable DNS Redirection, without having to re-configure the DNS settings of
each LAN client.
