Traffic shapping with pf hfsc and prioritizing based on group

[Gloomy Group]

Hi,

       As I'm new in packet filter I will like to get some help in setting 
my configuration for bandwidth shapping with altq hfsc. Below will be my 
network layout;

                                          VSAT for uplink only
                                            |
                                       Router
                                              |
                                   -|------Normal Switch------------------|
                                    |                                     
DVB for downlink
                                    |
                                rl0 interface
                                            |
                                           Freebsd shaper/gateway
                                                        |
                                                    rl1 interface
                                                       |
                                                     Switch
                         
|---------------------|---------|---------|-------------------|----------------------------------|
                         Dialup users   Cable users       webserver    proxy 
servers       Wireless users


  What I want to do here is rl0 interface will be used for shapping uplink 
traffic whereas rl1 interface will shape only downlink traffic to my network 
group. Cable users will get higher priority than wireless users. Has anyone 
got sample configuration with this network layout?
