IP Tables State (iptstate) was originally written to implement the "state top" feature of IP Filter in IP Tables. "State top" displays the states held by your stateful firewall in a top-like manner.

Features include: - Top-like realtime state table information - Sorting by any field - Reversible sorting - Single display of state table - Customizable refresh rate - Display filtering - Color-coding - much more...

To use iptstate, CONNTRACK should be enabled in your kernel.
