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.
