No subscription is currently needed, though that may change.
Many moons ago it used be about £35 a year subscription, its was all done via the routers MAC address through the router, but its been free for about 3 years now, but who knows if that will change, either way at £35 a year it was still damn cheap compared to some others.
The draytek will do all that you want and much more, but it can be a little complex to start with.
I have managed with much trial and error to set mine up to limit 3 different groups of people in my house, the kids, me and the misses, and the adult daughter. each profile has different web rules, IM rules and different rules at different times of the day.
best thing to do is write down what you want to achieve and make a plan first before attempting anything - also start with a few simple filters to get a feel of what happens and when. You can also ask questions here and someone (maybe me if I see it) will be happy to help, although it is sometime quite difficult to explain things. Its a shame these boards dont do PM's as I would be happy to talk through things over the phone, but I'm not posting my number here!!
