hello. i have iptables rules on my home linux router and i want to do a statistic from it.

is it posible to send variables from iptables to web server and then work with this variables?

example:
when i type iptables -nvL on my router, this come up:

Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)
pkts bytes target prot opt in out source destination

446K 91M ACCEPT all -- * * 0.0.0.0/0 0.0.0.0/0

it say, that 91Mbyt has passed through my linux router to my PC. and i want to send value 91M to my web server and make statistic from it...

thanks

You can use mrtg to create statistics from the router ( if the router support this)
http://oss.oetiker.ch/mrtg/

You might try:
BYTES_IN=$(/sbin/iptables -nvL INPUT | grep -m1 "ACCEPT all" | cut -b 7-11); echo $BYTES_IN > /tmp/bytesin

and refer to /tmp/bytesin on a web page. You could set a root cron to run the above every couple of minutes to have updated information in /tmp/bytesin

but when i want to monitor two PC behind router, mrtg can not help me
