Configuring The Dns Proxy; Configuring Dns Spoofing; Configuration Prerequisites; Configuration Procedure - HP A5120 EI Series Configuration Manual

Configuring the DNS proxy

Follow these steps to configure the DNS proxy:
To do...
Enter system view
Enable DNS proxy
Specify a DNS
server
NOTE:
You can specify multiple DNS servers by using the dns server command repeatedly. Upon receiving a
name query request from a client, the DNS proxy forwards the request to each of the specified DNS
servers in turn. A DNS server configured in system view has a higher priority than the DNS server
configured in interface view. That is, the request is first forwarded to each DNS server configured in
system view. If no reply is obtained, the request is then sent to each DNS server configured in interface
view in turn.
