Hi all, I am using FreeBSD 5.2.1-RC + IPFW2 + DUMMYNET to do traffic shaping. This works well for my setup. I have the following configuration: The machine has 2 NIC's, xl0, dc0. The kernel is configured to do bridging. The bridged packets is passed to IPFW (net.link.ether.bridge.ipfw=1). I shape traffic this way: The bridge is setup between a router and an internal mail server. I am limiting bandwith using the following rules: pipe 1 config bw 16KBytes/s pipe 2 config bw 12KBytes/s and then: add pipe 1 tcp from any to any 25 (limit incoming traffic towards smtp) add pipe 2 tcp from any 110 to any (limit outgoing traffic from pop3) Yesterday, while browsing through Absolute BSD by Michael Lucas I read an interesting part: You cannot shape incoming traffic the way that I do at the moment. Now, my question: How can I limit the incoming traffic towards my smtp server properly? Any advice would be apreciated. Thank you, Regards Jaco van Tonder
