We also did this a year ago. Although we had been advertizing the proxy for
half a year (a monthly request) about 60% didn't care. So we announced that
it was mandatory to use proxy, explained how to use it in a help file and a
week later just blocked. It took about 3 days and 99.9% of the users
understood there was no way out (nice to see on an analyser people just
trying for a while although they couldn't have missed the announcements). We
got about 2 help-requests (on about 300 users) and that was it. Now people
