I am wondering if its possible to see the data usage for the static IPs I have on my network using the RouterBoard 750? Even better if I can see the websites? But im really more concerned at being able to know how much a certain IP has uploaded/downloaded.

Thanks

IP Accounting / NetFlow / Firewall Rules.... Many ways to do this...

Whats the best way to do it? i find accounting contains too much and all mixed up. what do u advice and how?

I just set Simple Queues for each IP and use it for monitoring. It may show you current bandwidth used by ecah IP, and also total upload and download. You may reset statistics manually, or periodicaly by script.
