<br>Hi all...... Help! :S<br><br>Both of my external DNS servers which are authoritative for inksystemsinc.com & inksystems.com, are also the same one I use for VPN users when they are logged in. Recursion requests are only allowed from a specific IP ranges, which include the internals and some private ranges. <br><br>I have updated, my FC8 version to 9.6-ESV-R4-P3, which I got from http://www.isc.org/, which I thought would fix the problem. But it has not. Am I missing something? I have googled around and I understand the problem to be a spoofed header, which is causing my server to DoS (I think facebook), but the only suggestion that came close to a solution was an iptables hack that looked quite ire. It has no affect on performance here, but I do want to be a good netizen so the sooner I can stop this the better.<br><br>I am in the process of updating the servers to version 9.8x, to see if that fixes the problem.<br><br>Any help would be greatly appreciated :)<br>Shawn<br><br><br><br> <br><br><br> client 66.220.145.241 query (cache) './NS/IN' denied: 4 Time(s)<br> client 66.220.145.242 query
