Sorry, can you describe a bit better what your setup is. I dont think it is clear exactly what your setup is. Then maybe we can give you a solution as to how to block internet access for a group of users

the simple way to do this would be to block port 80 and port 443 outbound from the remote site. However this would disable access to any internal web applications, obviously.

If the user PCs run Windows and are part of a domain, you can configure proxy settings in their web browser and lock this down through group policy. If using Firefox the add-in called PublicFox can do the same thing.
