DNS Proxy Server

When DNS Proxy is selected as the DNS Relay Source on any LAN-side
interface, client devices will send all DNS requests to this Router LAN side IP
Address.
The router checks the Local Host Table for any pre-configured Domain Name
lookups, and if a matching entry is found, responds with the corresponding IP
Address.
When there are no matching entries in the Local Host Table, the router
initiates a Proxy DNS Request using its System DNS Client, then generates a
corresponding DNS response to the LAN-side client with the corresponding
IP Address learned via the Proxy Request.
Figure 14: Displaying the DNS Proxy Server (default shown)
The Host Names of locally attached devices are dynamically learned and
automatically populated in the DNS Proxy Table. Domain Names must be
statically configured. The entire Domain Name must be configured (e.g.
discovery.microsoft.iptv.com) along with the IP Address that should be
returned to the local clients to send a DNS Request for that Domain Name.
