Title:
  Ubuntu 20.04 - Network Manager blocks port 68 so our device agent is
  not able to complete DHCP Discovery

Status in network-manager package in Ubuntu:
  New

Bug description:
  Network Manager blocks port 68 so our device agent is not able to
  complete DHCP Discovery

  we have a component by name DCA-Enabler which does DHCP Discovery and expects 
response on port 68, this is generic DHCP behavior port number 68 is used by 
the client to receive (DHCP) server responses.
  Refer https://en.wikipedia.org/wiki/Bootstrap_Protocol  

  In older Ubuntu versions like 16.04, 18.04 etc. Network Manager does not 
blocks port 68 so DCA-E is able to read the responses.
  In Ubuntu 20.04, As network manager has already occupied port 68 it gets the 
DHCP response but DCA-E does not gets access to the port and cannot read the 
response. 

  So let us know what could be the solution for this, is there a way we can 
call network Manager API and read the DHCP Discovery response ?
  Or can we have a call with Canonical and understand on this change in 
behavior ?
