Increase nf_conntrack value

Hey guys, sorry to bother you with this newbie question (maybe?), but i'm pissed off right now.. can't find any good information on google.

I want to edit the nf_conntrack value 'cause I'm being DDoSed and my /var/log/messages says nf_conntrack is full...

I know how ip_conntrack can be modified.. but I can't figure out how to edit nf_conntrack (installed FC 7...)

Thanks alot guys

ps: if there are any additional settings i must edit on apf to work with nf_conntrack please warn me about it.

Have you tried echoing a higher-than-default value into the file? For example:
echo "64000" > /proc/sys/net/netfilter/nf_conntrack_max
