## Hardware-Accelerated Monitoring Functions
The FPGA/NXP card shall detect UDP packets containing DNS queries (UDP/53) in the incoming traffic received through the external interface E. These packets shall be (1) sent to one of the internal interfaces, say A, but also (2) passed to additional hardware processing. Other packets will be sent directly to the other internal interface B.

The DNS server running on the host machine shall listen on both interfaces of the Intel card and route all responses back to the interface connected to the internal interface A. The FPGA/NXP card shall (1) send each response out of the external interface E, and (2) pass it to hardware processing.
