hmm I have only seen appliances as traffic shaping between vlans so cant help you there... but I have seen degregated performance by using the voip provided router and running a computer off that as well. Setting up a switch and hanging the voip box off that took care of the problem. If you already have a switch in place maybe you could look at QOS and configuring the switch to dedicate so much bandwidth to the VOIP traffic. <div class="gmail_quote">On Fri, Mar 7, 2008 at 10:58 AM, (``-_-ДД) -- Fernando <<a href="mailto:ubuntu@bugabundo.net">ubuntu@bugabundo.net</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Hi there. What is the best way to do traffic shaping in Ubuntu (hardy in my case)? I've been using trickle and trickled but getting no where. I need to limit my outgoing bw, so I dont affect other users and the VOIP system. Can you help me?
