LINUX: Iptables/netfilter Connection Tracking

[Jeremy Fowler]

Alright, just thought of a Linux related question to ask... ;-)

I know there is a library (libiptc) that gives an interface to the netfilter
tables that you can use directly from a program. Is there a similar library that
gives you an interface to the connecttrack module and lets you see what packets
are being DNATed and SNATed dynamically?
