iptables -t mangle -A PREROUTING -p tcp -m mark ! --mark 0 -j ACCEPT
That section after the restore-mark rule will cause any saved marks to skip the rest of the chain. This results in only the first packets of a tcp connection having to hit their individual --set-mark rule. If you do have concerns about cpu usage or some such, I'd suggest trying trying out the ipp2p match module instead of the more generic l7match module. It's more specific to p2p and tends to be much faster than doing regular expressions.

I have a script that makes connections for every user with his auth. So, in this script, I have two mark tags. Can I use this tip you give to ro0ot? My doubt is if I use this every time some user log it will be all executed again, it will not make me trouble?
