      Hello I have pfSense 2.0.2 installed and operating in bridge mode. I have floating rules as well as a rule under wan and opt1 to block ports 66-69 for the floating rule I have the option for apply immediately on match and the block dhcp rules are listed first above all other rules.

      I run (dhcpfind) on the wan side of the pfsense box to see if it is correctly blocking dhcp from exiting the wan link and every now and then I find that it is passing dhcp requests through the wan side from the lan ip/subnet. Is there a way to block this behavior completely?  I have already reset the box and states after I made the rules.
