I do this:

iptables -t mangle -A PREROUTING -j CONNMARK --restore-mark
iptables -t mangle -A PREROUTING -somerules -j MARK --set-mark xx
iptables -t mangle -A PREROUTING -somerules -j CONNMARK --save-mark

Generally, i have separate tables that do the mark/saving so as to only put the rules in once.
I also have a route for the local net in my fwmark(ed) tables.


Hope that helps

John
