Nope, not at all. If you think this has been fun for me, you are quite mistaken.
I will be having FaunaClassifieds moved to a new server and hardened network sometime early this week. As to whether it will fix the problem of some people being blocked, I really don't know. DDoS is a serious problem that most people are not even aware of. I know I sure didn't know much about it beforehand.........
Sorry Wes, but if you are being blocked from the site, then the only explanation is that your IP address is being spoofed as being the source of some aspects of this attack. The program code can only block via IP address and has no way of telling if it is legit or not. Seems kind of odd that out of all the many IP addresses available that there would be a lot of hits on REAL users. That does bring up the interesting possibility that whoever is behind this wants to smack you down to in relation to the site and somehow knows your IP address.
Oh, and for the record, whatever it is you have done has NOT changed your IP address here at all. So you are still using that original IP address over on Fauna as well. Have you tried just bypassing the router and going direct to the modem? If the router is changing your IP address, you may want to try that.
