Hi Alex,

Yeah I got that bit ;)

What I don't understand is with my current configuration why isn't the
accounting "counting" anything to do with the virtual ip's on eth1
202.45.102.90 and 202.45.102.70 there the IP's that should be getting all
web traffic for those sites and then keepalived balances them over the nat'd
servers on eth2.

    Hello Adam!
    For begin as i understand you must start one 'pmacctd' daemon (with
own config) for every interface that you must accouting traffic. In
configs you must set up relative interface, aggregate_filter, aggregate
and other parameters.
