Comment (by anonymous):
Actually, a DHCP client renewing it's lease will initially try to reach
the server using unicast but will fall back to broadcast if that's not
possible. Definitely some weird network configuration there, probably some
relay involved. So in the latter case you don't have conntrack kicking in
and the reply will have to be explicitly let in using the above ACCEPT
rule. So it does make sense keeping the rule around.
