sorry i could not help, maybee what your going to need to do is have some very basic rules in your iptables firewall that just count packets , with the iptables option for doing just that ,, e.g. although we might already be allowing the flow of this Traffic, it does hurt to add a rule that like counted all TCP packets or in this case all packets From squid to the LAN $IPTABLES -A OUTPUT -o $INTIF -s $INTIP -d $INTNET -p tcp --sport 3128 -c 0 0 -j ACCEPT this works great for me, because i have a script that every 2 hours it logs & rests all my traffic. and also one in my ip-down.local for when my modem gets disconnected ... hope thus helps :D
