What if you add:

add allow ip from any to any frag

instead the line above?

add check-state
add deny icmp from any to any frag

I'm not sure the line above is correct.

add allow icmp from any to me icmptypes 0,3,11
add allow icmp from me to any out keep-state
add allow tcp from me to any out keep-state
add allow udp from me to any out keep-state
add deny ip from any to any

It looks like dynamicaly created rules some how inadequately handles big UDP 
packets (DNSSEC answers are big).
Is there any who can help to investigate this issue (looks like I can't do it 
myself)?
Can it be ipfw related issue?
