How can I calculate how much traffic goes through my router?
As I have more internet than I can use myself and I have free router I don't use I was thinking about making a free hotspot for the neighbors. Unfortunately, my traffic is limited though so I'd like to have some limits for its day usage. I will install dd-wrt or openwrt on the router to do that but last time I was trying to calculate traffic usage under Linux I had to write my own ulog filter for netfilter and I'd like to avoid doing so now. So is there a product I can use to achieve my goals i.e. break all connections for a day when limit is hit (or shape them down to 32kbps)?
