I would like to restrict the number of hours users on my network can access the internet.
I have a Vigor 2820 router and can hard-set what hours they can go online and what they can do etc, but I'd like to make this more flexible :
I.E. I'd like to say to them "You can use 3 hours of internet today" and they can then spend that 3 hours at any point during the day. I dont think the Vigor can do this flexibility.
I've been on holiday to parks where you can purchase X hours online, and its that kind of thing im looking to do, albeit on a much smaller scale.
I understand that this may involve use of an inhouse proxy server, likely to be linux based and that isnt a specific problem but my unix experience is basic to intermediate.
Any ideas ?
