Is the class added to the interface manager for the interfaces?, and saved at the top?
Is the load balancing enabled at all on the load balancing section? if so, i don’t think qos can work then? you’d need Atheling’s NB-QoS patch to make both work at the same time. To be honest I’ve only used QoS in bridge-mode to shape transparently. I have used the NB or in route mode at all, but i would think it would be very similar setups.
