I didn't spend much time with the ASUS WRT firmware before re-flashing my RT-AC68U with DD-WRT, but one thing I really liked was the Traffic Analysis - static page it had in the interface.
Does anyone know what software/firmware package is being used to present this info? Is this package or these reporting tools available on DD-WRT?
I have seen links to Rflow and Netflow, but those appear to be external to the firmware running on the router. Perhaps I'm not understanding how they operate.
I'd really like to get this or something similar running on the router.
Yes - YAMon 3.x has an install script that walks you through the initial setup and configuration process. The thread linked above has lots of info. See also http://usage-monitoring.com for more info.
