How would you achieve this setup ?
I can only think about this way (assuming gif0 tunnel packets flow thru
ep1) :
ext_if="ep1"
tunnel_if=gif0"
altq on $ext_if bandwidth 2Mb cbq queue { dflt, developers, marketing }
queue dflt bandwidth 5% cbq(default)
queue developers bandwidth 80%
queue marketing bandwidth 15%
pass out on $tunnel_if from 192.168.0.0/24 to any keep state queue developers
pass out on $tunnel_if from 192.168.1.0/24 to any keep state queue marketing
But in this setup classification is made on unencapsuled packet, and
shaping is done on encapsulated packet. Does this mean that the mbuf tag
set by classification rules survives the gif encapsulation process ?

Ok.

I'll have a look.

Ok, thanks to you and Brooks for explanations.
