DNS proxy configuration example

Network requirements

When the IP address of the DNS server changes, you must configure the new IP address of the DNS
server on each device on the LAN. To simplify network management, you can use the DNS proxy
function.
As shown in
Specify Device A as the DNS server of Device B (the DNS client). Device A acts as a DNS proxy.
•
The IP address of the real DNS server is 4.1.1.1.
• Configure the IP address of the DNS proxy on Device B. DNS requests of Device B are forwarded
to the real DNS server through the DNS proxy.
