E.g. if you run "tcpdump -n -i eth1 dst host 192.168.42.1" does it show anything? I suspect that almost all your traffic is actually destined to hosts out on the Internet, especially as you are looking at the external interface. I would not expect to see any traffic destined for 192.168.42.1 arriving on the public interface, as your ISP should not be routing such traffic to your connection. > I only what to graph all the income (sum of) and outgoing (sum of) > traffic passing through eth1 / 192.168.42.1 > In short I want to graph the network utalisation of the public > interface so I can see if the adsl is being maxed out. > How could I do this ? You should already have it. Just add up the traffic for each source address with a SQL SUM/GROUP BY and it will give you total traffic for all hosts.
