<DIV>Hi All,</DIV>
<DIV> </DIV>
<DIV>Instead of measuring in a forwarding rule... Perhaps just an input
rule on the interface connected to the adsl/cable connection. As then you
are not counting the traffic between the other tenants. Coz if u play
games etc or have other comon resources that u share, it will all count
& u r not sure who has actually used the common cable bandwidth.</DIV>

one chain for machine of interest, plus a common upstream
