Hello ...

We have a Vigor 2952 router which supplies two different areas on different IP address ranges 192.168.1.xxx for one and 192.168.0.xxx for the other. One of the group of users wants to be able to limit their childrens use on the internet eg 2 hours each evening on the 1.1 range

Firstly can this be done without affecting the other IP address range - they want access 24/7 and dont want to have to login etc.

Is that possible???

You can use firewall rules to block / allow internet access on the 1.1 range based on a schedule.
