I have Netware 6 server with BM 3.6 installed, Im wondering if I can

restrict access to internet only in certain hours o time interval. Per

example I want that my users only can access to internet from 3:00 to

5:00. BM is configured as proxy, and NW6 is DCHP server, did I need to

configure something else?.
Is this possible? And if it is possible, where can I configure this.
Thanks in advanced
