I am trying = to shape multiple TCP connections to 56K from one 100MBit pipe. CLIENT ---------- ETH0 -------- ETH1 ---------- SERVER 192.168.1.1 192.168.1.254 172.16.1.254 172.16.1.1 For example, I want the client to be able to make multiple TCP = connections (.1.1:80, .1.1:8081, .1.1:8082) all at 56K from the server, which = obviously has the ability to deliver 100MBit. My CBQ file looks like so: DEVICE=3Deth0,100MBit,10Mbit RATE=3D56Kbit WEIGHT=3D5Kbit PRIO=3D5 RULE=3D192.168.1.1/24:80 RULE=3D192.168.1.1/24:8081 RULE=3D192.168.1.1/24:8082 RULE=3D192.168.1.1/24:8083 RULE=3D192.168.1.1/24:8084 RULE=3D192.168.1.1/24:8085 Is it possible to use iptables to make all the connections' destination ports appear to be port 80? How, and to which interface, should I = apply the rules? Also, when is CBQ applied? Prerouting? Postrouting? Is it applied pre- = or post-routing specific to the interface, or to the kernel?
