It won't stop you from saturating the pipe with incoming traffic. so you'd have to set up queueing on the interior interface of your firewall as well... tcp will throttle back to this cap, but ordering up a fat udp stream will always get you in trouble. /k

Re: using queues to limit bandwidth
I forgot to mention in my previous e-mail, that if you were to implement the scenerio outlined in your e-mail, then the other company would have to 'trust' that you're setting up your firewall to not exceed your 100k of bandwidth. Just setup a single queue that caps at 100k. On 5/1/06, Chris Bullock <[EMAIL PROTECTED]> wrote: Can queues be used to queue overall bandwidth?

Yes, CBQ works quite well. http://www.openbsd.org/faq/pf/queueing.html#cbq -- Jason Dixon DixonGroup Consulting http://www.dixongroup.net

ALTQ Should do the trick: http://www.openbsd.org/faq/pf/queueing.html On 5/1/06, Chris Bullock <[EMAIL PROTECTED]> wrote: Can queues be used to queue overall bandwidth?

using queues to limit bandwidth
Can queues be used to queue overall bandwidth? We have a project where we will be sharing an Internet connection with another company, we will have an IP and they will have an IP each company providing their own firewall. I understand that queuing is able to queue based on protocol, etc on the same box but lets say there is a T1 shared between the companies, The company tells us, you can have one of our IP addresses but you can only use 100k of our bandwidth, can pf do this?
