Hi, everyone. I''m newbie to TC. Now, I want to control my gateway traffic with tc. I have a typical linux gateway server (CentOS 5) Requirement is as follows: 1. Total bandwidth is 10M (either up or down) 2. Each PC in the subnet (192.168.0.0/24) should be limited to 1M bandwidth, so that no single PC can expend too much bandwidth. How can I carry it out? I am not quit familiar to tc. After reading some articles, I find set-mark with iptables and handle mark with tc might be good. Must I add more than 250 rules in iptables or tc? Does it result in low efficiency? Massive thanks. Best regards, yfang
