Where is the correct place to set net.netfilter.nf_conntrack_buckets?

http://serverfault.com – I'm currently trying to set net.netfilter.nf_conntrack_buckets on boot. I initially assumed that this could be done through sysctl.conf, but net.netfilter.nf_conntrack_buckets (and other net.netfilter configurations) were not applied at all. Adding sysctl -p to rc.local allowed all the net.netfilter configurations to be applied with the exception of net.netfilter.nf_conntrack_buckets. I'll also note that trying to set this from the terminal using sysctl -w results in 'error: permission denied on key 'net.netfilter.nf_conntrack_buckets'' # This should be applied at boot net.netfilter.nf_con (HowTos)
