[mrtg] Using filters to compare src and dst addresses at the same time

I've been tinkering with the flow-report, stat.cfg and filter.cfg
to create a Netflow system that only tracks internet
traffic. On our network we have multiple address ranges
that are tracked by the Netflow collector. Currently we are
tracking traffic by the dst address and filtering the traffic
to ip's on our network which in turn gives us the download
However my intention is to eliminate the tracking of on-net
Flows by comparing the following
If the DST and SRC are on-net then deny.
Any thoughts on how I can manipulate filters.cfg to do this?
P.S. I know it would be really simple to change our network
so that on net traffic does not flow through the main (Netflow) core
router but at this stage it is not an option :-(
Any thoughts would be well appreciated!
