linux router statistics

[hapoo]

Ok, not sure if anyone can help me on this but i'll give it a shot. I'm using netfilter (iptables) and i'm looking for a program that can provide me with statistics like amount of data in and out of each IP and NIC, speed stats, monthly transfers, stuff like that. Anyone know of such a program?

Maybe Ethereal (http://www.ethereal.com/) or Sniffit? (http://reptile.rug.ac.be/~coder/sniffit/sniffit.html)
