Double check the kernel version you have. IIRC kernels before 2.6.20
didn't have the ability to do RELATED,ESTABLISHED in ipv6. This hit
me on a CentOS box that I was using as a gateway. I am unaware if
there is a version of their 2.6.18 that has the patches backported
(googling seemed to indicate it has not been done, and most are just
waiting for new release of CentOS 6). RH6 works properly.
