WAG300N QoS

Hello
I would like to check if my understanding of the WAG300N QoS funtionality is right.
From what I see on the manual, with QoS I can have priority only on the outbount traffic (this is anyhow what I would like to have, QoS applied only to outbound traffic).
Is this correct: no limitation on the inboud?

thanks, best regards
