OK, here is the situation:
We have an external proxy (LEA) and a basic internal proxy (software - browsegate). Current internet setup works fine, however we recently installed new PCs in the Library. Because this room is essentially "open all hours" we wish to restrict internet access in there to specific hours. How would you go about doing this?
I have experimented a little with Smoothwall. The library machines have their own dedicated switch, is there something I could put between this switch and the network?
Also, ideally, any solution would need to be easy to access and modify (ie for teaching staff).
Any help and suggestions would be much appreciated!
