That looks reasonable to me. What version of firehol are you running?
Can you post the output of running: firehol debug? Running that config
snippet, I get these rules in the output according to firehol status:

Chain in_LAN_DHCP (1 references)
    pkts      bytes target     prot opt in     out     source               destination
