http://serverfault.com – I am sharing a ADSL connection with my friends using a ZTE w300 wireless router. However as many people are sharing the connection when one person is downloading the bandwidth cannot be throtelled. I have come across firmware such as Gargoyle router,Openwrt however the website doesnt say that it supports the above router. can anyone suggest a software or a firmware which has the ability or monitoring and throtling the bandwidth per user/ip (HowTos)
