So I setup PCC with 2 ISPs and it's working great. Each ISP has different bandwidth limits. The cable connection has 5meg down and the DSL has 3meg down. I setup up mangle rules so that each connection stay within it's limit and that is working fine. I now have a new problem though. When I disable one of the interfaces forcing all connections to go out just the one internet connection. PCC is still marking for both internet connection 1 and 2 which causes QoS to be limiting for both connections even though there is one connection active. So my question is how do I prevent PCC from marking for connection one when it's not online?

Make a script that disables the appropriate rules, and it's counterpart. Use netwatch to watch the gateway IPs and run the scripts on up and down events.

Edit: alternatetively have the scripts change the QoS queue sizes to match the new situation. This may be easier.

Good idea. thanks.
