See how much bandwith is being used on my gateway

[iverasp]

Hi. I've set up my own box as a gateway/firewall to the internet. I wondered how I could see what amount of bandwidth is being used, and how much data that have been downloaded this month etc.

It would also be great if I could in some way reserve an amount of bandwidth for my VoIP phone, so the sound doesnt lag when downloading.

Thanks

I do believe that kind of information is in /sys. Reserving bandwidth can be done with QoS, google for WonderShaper.

For monitoring you can try "darkstat". Nice webalike interface.
