We have kernel support for IPv6 in Centos, but not stateful firewall support.
That requires at least the 2.6.20 kernel, which means Fedora Core 6 or some other Linux distro.
None of the various free Linux firewalls have IPv6 support. Supposedly FWBuilder can manage Netfilters for a Linux Kernel, but that seems to be the extent of it.
More sad facts as I uncover them.....

Just use openbsd. We cannot expect Linux to rule everything. Use what best fits the job.

Not sure about FC6, but in both CentOS 4 & 5 there is an ip6tables. I haven't used it, but I'm assuming that you can build rules just like you do with iptables.

My dd-wrt web page has a IPv6 checkbox, but don't know what it does. i am shunning IPv6 bc securing the private side of a NAT is hard enough. Securing IPv6 seems much much much tougher.

The OP is not saying there is no ipv6 netfilter support. He said that there is no ipv6 state netfilter module or something like that.

What he originally said was that this needed kernel 2.6.20 or newer. Is this one of the feature backports into the enterprise kernel that Centos inherits?

Exactly!!! What he's complaining about is the lack of lazy-man's GUI tool to configure ip6tables.
Are you absolutely sure that FWBuilder doesn't support IPv6? Because here there a release note http://www.fwbuilder.org/docs/firewall_builder_release_notes.html referring to ip6tables.

Not so much as complaining, but looking at easy-of-use and time allocation.
I have done iptables by hand and have used a few tools. One thing I like about the tools I have found helpful is they have been good 'quick starts' for learning what to do by hand!
But my source is: http://www.guug.de/veranstaltungen/ecai6-2007/slides/2007-ECAI6-Status-IPv6-...
Peter, who has been involved with IPv6 for a long time, covers NetFilter on slide 8 and claims stateful support added in 2.6.20. Elsewhere I found a reference that RHel would get this end-of-year 2008, and Fedora Core 6 has it now. I looked in my /boot and saw that Centos is using 2.6.18, and I concluded from all this that I would have to work with FC6 for the next half year. Seems this conclusion is mis-informed if this NetFilter feature got backported already....

I also saw that FWBuilder supports IPv6. But if the kernel only supports stateless, then that is all you can do with FWBuider, I would think. My one review of FWBuilder was that it was more than I needed at the time and Shorewall would handle my needs for my one VoIP firewall. Well I learned a lot using Shorewall. And Shorewall does NOT have IPv6 support, I asked on their list.
So now I go and build a box and see if I got enough to get the job done.

There is one thing to remember about Enterprise RedHat; you can't just assume what is in it by package version numbers alone. You have to read changelogs, and sometimes the patches themselves. Or just try it and see if it works or not.

I may be ethnic Chinese but I grew in Sierra Leone and English is what I use from day to day and I cannot read Chinese characters...or do not recognise enough to claim literacy anyway.

When did I or the OP say there was absolutely no ipv6 support?
