Hi

Create an accounting chain:

IPTABLES=/sbin/iptables

### accounting chain
$IPTABLES -N accounting
$IPTABLES -A accounting -i eth0 -d $IP_INT_MAIL -j RETURN
$IPTABLES -A accounting -o eth0 -s $IP_INT_MAIL -j RETURN
$IPTABLES -A accounting -i eth0 -d $IP_INT_WEB7 -j RETURN
$IPTABLES -A accounting -o eth0 -s $IP_INT_WEB7 -j RETURN
$IPTABLES -A accounting -i eth0 -d $IP_INT_WEB1 -j RETURN
$IPTABLES -A accounting -o eth0 -s $IP_INT_WEB1 -j RETURN
$IPTABLES -A accounting -i eth0 -d $IP_INT_WEB3 -j RETURN
$IPTABLES -A accounting -o eth0 -s $IP_INT_WEB3 -j RETURN
$IPTABLES -A accounting -i eth0 -d $IP_INT_WEB4 -j RETURN
$IPTABLES -A accounting -o eth0 -s $IP_INT_WEB4 -j RETURN
$IPTABLES -A accounting -i eth0 -d $IP_INT_ORA2 -j RETURN
$IPTABLES -A accounting -o eth0 -s $IP_INT_ORA2 -j RETURN
$IPTABLES -A accounting -i eth2 -s $NET_INT -d ! $NET_DMZ -j RETURN
$IPTABLES -A accounting -o eth2 -s ! $NET_DMZ -d $NET_INT -j RETURN
$IPTABLES -A INPUT -j accounting
$IPTABLES -A FORWARD -j accounting
$IPTABLES -A OUTPUT -j accounting

Then to see the traffic use:
/sbin/iptables -nvL accounting
