Internet traffic monitor for Gnome/KDE

Hi,
I'm currently using a router inside my LAN for internet access.
But I've a volume-based internet access, so I'm forced to record all internet traffic, wheather it's in or out.
Actually, I've used iptraf before, but unfortunately it's a bit too pedantically (enter admin-pw, set up the options, copy traffic, paste in file) :? .

=> Is there a good internet traffic-monitor tool available for Gnome/KDE? It should have filtering options, the LAN-traffic is not interesting ;-)...

Well what kind of information do you need?
Obviously source, destination, time, etc. but is there anythings specific that you want to make sure is recorded?

I only need the traffic stats:

internet traffic (all) OUT
internet traffic (all) IN

Time would be nice, but traffic is more important. Do you know some handsome programs for that?
