[netflow-tools] ipv6 filtering - unwanted addresses showing up - SOLVED

I figured this filtering system out. I think the docs need better examples.

If I want all destination addresses to match a local subnet or 2 from 
2012-01-12 18:00:00 to 2012-01-12 19:00:00 is :

discard quick before date 20120112180000
discard quick after date 20120112190000
accept quick dst 2001:xxxx:xxxx:xxxx::/56
accept quick dst 192.168.0.0/19
discard all

Regards,
Otto.
