I've posted this here on the off chance that someone can help.

I need advice on setting up a mini isp.

Scenario:

Medium sized accommodation complex with 75 units.
3 bedrooms per unit each wired with Cat5 back to a secure room.
Only type of internet available is cable.
Telco will provide cable in from road and approx. 30 cable modems on a 10Gb per month plan for each modem with a maximum of 8 users per modem each with their own IP. (Yep bandwidth isn't good in Aussie)
Telco will only offer this setup, will not provide any other solution.

I need to be able to provide hardware and software to be able to manage everyone and limit each user to 1Gb upload/download a month whilst at the same time allowing them to use more if they need it.

Because this is the only setup available, no one else seems to have done it before.

I thought of using 5 x 48 port switches and a server hooked into it but have no idea of the software need to manage it all.



Any ideas greatly appreciated.
