In SA we pay for bandwidth (speed) and the amount of data you download, e.g. 3GB.
I want to make a small ISP to share my internet with a few people. However I need to be able to cap (stop their internet) after they have exceeded a set maximum of up- and downloaded traffic.
I will be using pppoe for the client to internet connections. Is it possible to cap clients with pppoe as well?
OR is their another way? It must be possible with iptables, dropping traffic from a certain source, but I have no idea how to implement that.
