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.

Since IP Tables doesn't have a built in way to easily display
this information even once, an option was added to just have it
display the state table once.

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
- Open Source
- much more...
