Hello, I'm not sure if there are documents on this subject but I'm trying an experiment with my box running 2.6.22. I want to bridge 2 Ethernet interfaces and sit between my router and my switch in my office. Be a man in the middle. I'm going to use the bridge to "cut" the wire and "tap" into it. I want to gather stats of all traffic going from my network to the router and the reverse direction as well. I also want to use QoS to shape traffic heading for the router and out the Internet. Here is the idea. bridge br0: Device eth0: Link to the router. apply QoS Device eth1: Link to the office switch. apply QoS. Will mixing these 2 cause issues?
