watch iptables counters

watch --interval 0 'iptables -nvL | grep -v "0 0"'
This will allow you to watch as matches occur in real-time. To filter out only ACCEPT, DROP, LOG..etc, then run the following command: watch 'iptables -nvL | grep -v "0 0" && grep "ACCEPT"' The -v is used to do an inverted filter. ie. NOT "0 0"

You can use watch to identify/highlight the changes between refreshes like this: watch -d -n 2 iptables -nvL It'll highlight (with a box over it) any changes since the last refresh.
