I'm trying to limit the time that my kid's computer can have internet access. I've setup an access rule using their computer's IP address. I only want to apply the rule for a specific timeframe (schedule). I can't get this to work. Selecting "Anytime" from the "Apply this rule" list does work, but when I specifiy specific times, the rule won't work. I'm using 24-hour formatted values as required. Any ideas? Thanks.
