Hello,

Are you using a 2.6.18 kernel image from Debian etch or a custom one ?

IPv6 conntrack requires the (now not so) new nf_conntrack, but in kernel 
versions older than 2.6.20 nf_conntrack did not support IPv4 NAT yet. 
Only the old ip_conntrack, the IPv4-only conntrack, did. So IPv6 
conntrack and IPv4 NAT were mutually exclusive. AFAIK 2.6.18 kernel 
images from Debian etch are built with ip_conntrack in order to support 
IPv4 NAT, and do not support IPv6 conntrack.

I am just a bit surprised that using the state match in ip6tables with a 
kernel without IPv6 conntrack support does not trigger an error.
