I hope i dont reinvent the wheel with this or that it is a faq: [...] i want to setup traffic accounting on my linux firewall. Use ipac-ng (ip accounting). You can find it on freshmeat and it does exactly what you need (and a little more with nearly no effort).
my short question is: will in effect the performance of the firewall in a bad way if all packets that enter / leave via eth0 have to pass through my accounting chain? I'm using ipac on my P120 router machine and it doesn't have any bad effect.
is my solution totally dumb (i tried ipac-ng, but was not happy with its configuration, means i was to dumb to get it to work properly)? Look into it again, many people like mrtg, but I was too stupid to configure it. Ipac-ng did the job for me. I may also send you my config file if you need it.
