Problem setting connmark with ip6tables

I am upgrading some software to IPv6 and am running into a problem
setting connmark with ip6tables version 1.4.4.


With iptables, I can do:

iptables -A PREROUTING -i sat0 -t nat -m dscp --dscp $i -j CONNMARK --
set-mark 99

for i = 0 to 63 with no problem.



If I change to ip6tables:

ip6tables -A PREROUTING -i sat0 -t nat -m dscp --dscp $i -j CONNMARK --
set-mark 99

I get the following error:


ip6tables v1.4.4: can't initialize ip6tables table `nat': Table does
not exist (do you need to insmod?)


What is the syntax to set the connmark with ip6tables?

Of course, as there is no such thing as NAT in IPv6, and consequently no
'nat' table.

I haven't tried it myself, but how about using the PREROUTING chain in
the 'mangle' table? It has a CONNMARK target.
