[netflow-tools] Filtering by IP

[Pete Bristow]

Hi
The filtering in flowd is very reminiscent of pf. I was wondering if it's
possible to have something along the lines of

internal_traffic = "{ 192.168.0.0/24 192.168.2.0/24 }"
discard src $internal_traffic dst $internal_traffic

If not what's the suggested way of doing this is as once you have more
than a few subnets the rule set grows quite large and I'd imagine quite
inefficient to run.

Thanks

Pete
