Netcraft stopped identifying my local FreeBSD site around 4.5. It is mostly used to test pages before I upload them to my ISP and to store large numbers of graphics images that would exceed my ISPs size limit. I did have TCP_DROP_SYNFIN set but removing it when it was first mentioned on this thread did not change anything. I also do not have RANDOM_IP_ID set. I am running ipfw+natd and I wonder if the way some rules were handled has changed and is affecting things.
