I monitor a number of m0n0wall boxes and graph their traffic using rrdtool / cacti. This works a
great and I've never had a problem.
I have one or two boxes that a IPSec tunnel between them. I would like to graph / monitor the
traffic over the tunnel, however it doesn't present itself as a network interface. Can anyone
suggest a quick and easy way to monitor the traffic over the IPSec tunnel.
