Sometimes you need to upgrade to the "business" class of service to have this be allowed. There is really no technical way for the ISP to find out if you are sharing your bandwidth when you're behind a nat firewall, but it is worth looking into because if for some reason they are an ISP who doesn't like this sort of thing, it sucks to get shutoff -- and some providers will refuse to sell you service again for upwards of 12 months after a disconnect like this which is a huge problem if you are in an area where your options of ISP are limited.
