Title:
  isc-dhcp-relay not forwarding replies from dnsmasq

Status in “isc-dhcp” package in Ubuntu:
  Confirmed

Bug description:
  I had dnsmasq running on a VM, with isc-dhcp-relay configured to relay
  dhcp requests to it; it relayed them fine, but not the replies. I
  found some sporadic reports of this, but no bug in ubuntu, so am
  filing one here.

  It should be straight forward to reproduce - setup a vm with a bridge
  inside the machine, give the host an ip address on the bridge, and run
  isc-dhcp-relay on the host to forward outside -> vm.

  dhcp-helper worked perfectly in this situation.
