The rules states to allow traffic on a particular interface inbound for
port 67 and outbound to any ip address to port 68.

Bootp is used is you are running clients that need an ip address and boot
information. The server listens on port 67 and the server responds to
the request by sending the information to port 68 on the client machine.
Bootp provides three primary functions:

        IP address assignment.
             Detection of the IP address for a serving machine.
              The name of a file to be loaded and executed by the client machine
