Ok, it is just a test i made,(took me some hours, but ok)
below config i made for router2.cgi in multi cfg config pulls every 2
minutes the packet stats from pfctl and dumps it after processing in a
nice mrtg graph.
the only thing it not yet does, is mesuring the out data (only in)
but the beginning is here.
now i am gonna try hack in several tools for getting IP packet stat from
lan machines..

tail -1 `
