any help on this matter will be greatly appreciated.
Cacti is good at this, and I think MRTG can do it, too. But neither
of those is simple to set up. I'd give them a try, though, you might
do OK.
Depending on exactly what numbers you need, NTop is also a
possibility. It's dead easy to set up, and it's capable of breaking
out separate interfaces. The level of detail will be enormous, but
it's actually (IMHO) much easier/faster to get running than either
Cacti or MRTG.
If you're good with any scripting languages, you might want to
consider just polling the kernel's interface counters, yourself, via
a regular 'cron' job. That might not be an option, though, depending
on your skill level.
If the problem is sorting out which traffic went through the pay
connection, perhaps IPTables could be used. Just an idea...
If the NIC sees all the packets you can get a rough approximation:
iptables -I INPUT ! -s 10.0.1.0/24 #<- your LAN net address here
iptables -I OUTPUT ! -s 10.0.1.0/24 #<- and here
run that at the start of the month, then
iptables -L INPUT -nv | head
iptables -L OUTPUT -nv | head
would give you the packets and bytes sent to (received from) non-local IP
addresses. Ugly, inconvenient, must be started at the beginning of the month,
data lost on reboot, all of which you could hack around with clever scripts, but
there must be a better way.
The better way is probably MRTG or similar, which are complex to install, then
work well and do what you want. I'd skip iptables, it's pretty ugly and high
overhead to do right.
