Default Help with pf.conf

Hello everybody.

I need some help with my pf.conf.
My goal is to have all traffic (inbound and outbound) placed in queues, to speed up some parts and to make sure some things wont take up all the bandwidth.

At the moment all my outbound traffic is queued as it should but not the inbound.

I´m sure i´v made some obvious misstakes since i´m quite new at all of this.

Any help would be greatly appreciated.

Thanks
