I figured out what the problem was.  I had compiled my dhcp server with USE_SOCKETS and am NOT running in a jail.

After a lot of searching the bug reports I came across an old bug that said that USE_SOCKETS was added for jailed dhcp servers, because they do not have access to bpf.  It also said that compiling USE_SOCKETS into a non jailed dhcp server will have unpredictable results.

I found out that the server will behave badly like it is being sent through nat out our the wrong port.   

&gt; You should specify more information about your setup, but generally you 
&gt; should be able to just insert a rule like &quot;ipfw add xxx allow ip from 
&gt; mynet/mask to mynet/mask&quot;, where &quot;xxx&quot; is the rule-number BEFORE your 
&gt; natd redirection rule-number and mynet/mask describes your internal network.
