I understood that ALTQ works only at the outgoing device (ti0 or ti1), too

If I adapt RED in interface ti0 and not ti1, RED works only outgoing packet from interface ti0 to Server.
or, if I adapt RED in interface ti1 and not ti0, RED works only outgoing packet from interfce ti1 to Client. 

How can i do adapt RED at ingress traffic from Server to interface ti0. Or outgoing and ingoing, interactively ?
