I don't think there is anything that tracks things routed through a gateway unless it goes out different interfaces. Do you have different internal/external interfaces? You should be able to pick up the counters from the router interfaces via snmp if you want the totals there.
I have a small network with two cheap dlink routers on it, one attached to a cable modem and the other to a DSL modem. I route certain data through the cable modem, and everything else goes through the DSL.
However, on the computers only have eth0 and I just use route commands on the individual computers to sort out what I want to go out through each modem. My default gateway is 192.168.0.254 and I custom route certain traffic through 192.168.0.1.
Ultimately, I have three kinds of traffic that I'm interested in counting from each computer on my network: internal traffic, from one computer to another (from 192.168.0.x to 192.168.0.y); external traffic through 192.168.0.254; external traffic through 192.168.0.254. I would like to look at a report on each of my computers and find out how much data each one has sent and received during the period in each of those categories.
