A couple of months ago, Comcast announced their 250gb monthly bandwidth cap. This didn't really concern me too much at the time, but now I've been watching a lot more streaming content, playing online games, downloading, etc. I'm concerned that I may be coming close to this limit. I'd like to keep track of how much I use each month, up and down. I have an AEBS as my primary router, a macbook and a mini. Is there any type of plugin for the AEBS that can track how much goes in and out of it? I DO NOT want to record LAN usage, just basically how much goes in and out of the AEBS's WAN port.
