Yes, I know, we can only shape traffic when packets are outbound and leaving, that is general rule, for each and every router device (not only BSD).
But how to apply this on pf? So, for IP packet from LAN to Internet, we set:
pass in on $int_if proto...... to..... set queue gueueLANtoINTERNET
this packet from LAN to Internet will be queued on $ext_if, whe it leaves device?
