[Cialug] Netfilter kernel differences

[Tom Pohl]

I'm really late to take notice, but is anyone familiar with netfilter switch between using ip_conntrack and nf_conntrack in its kernel modules?

I'm more curious than anything as to what the major differences might be between the two mechanisms.  I run centos servers for the most part, so I'm still on the old skool ip_conntrack, but wonder what netfilter goodness I might be missing out on :)

Thanks!
