Hi all. I am using DUMMYNET for some bandwidth management - it's great. I'm now trying something new with it, and I'm not sure how it is behaving. I want to allow all users on the LAN to browse (ports 80,443) outside of working hours, but during working hours this should be stopped. Originally I added jobs in cron to add and remove the "ipfw add pipe x from $lanip to any 80,443" rule at certain times of day, and re-instate it at other times. It worked fine, but then I would lose the counter values from those ipfw rules. Now I have changed cron to simply change the pipe config on the fly :"ipfw pipe x config bw 32Kbit/s" to open it up, and :"ipfw pipe x config bw 1bit/s" to shut it down. This way my counter values continue to accumulate - GREAT! The problem is that the pipe seems to dislike the idea of running at 1 bit per second. Obviously this is rather extreme! Any suggestions on how I should best address this? Is there perhaps a practical limit to the minimum bandwidth which DUMMYNET is comfortable to work with? PS: you probably think I'm crazy fighting with such tiny numbers, but down in the South of Africa bandwidth is still a very expensive commodity! Regards, Patrick.
