Configuring The Dns Proxy; Configuring Dns Spoofing; Displaying And Maintaining Ipv4 Dns - HP 830 Series Configuration Manual

Configuring the DNS proxy

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 the DNS server that has the
highest priority. If the DNS proxy does not receive a reply, it forwards the request to a DNS server that
has the second highest priority.
To configure the DNS proxy:
Step
1. Enter system view.
2. Enable DNS proxy.
3. Specify a DNS server.

Configuring DNS spoofing

DNS spoofing is effective only when:
The DNS proxy is enabled on the device.
•
No DNS server or route to any DNS server is specified on the device.
•
To configure DNS spoofing:
Step
1. Enter system view.
2. Enable DNS spoofing and specify the
translated IP address.
