IPv6 connection tracking

Hi,

I have a problem with connection tracking for IPv6 in a vanilla kernel
2.6.17 and iptables 1.3.5.

iptables accept the rule fine, but the connection tracking is just not
working. It is still behaving like a stateless firewall. I have enabled
everything in the kernel that I could find relating to this.

Searching the net I came across some references to the option
NF_CONNTRACK_IPV6, but that option is not in my .config so I'm a bit
confused. Perhaps this is from an older patch? What do I need to do to
enable connection tracking for IPv6. Or does it simply not work yet in
the latest vanilla kernel?

Regards
