I use Shorewall on Gibraltar (Debian based) for a small home network. I 
use traffic shaping/QoS to downpriotize certain types of traffic (Wonder 
Shaper, htb version as described in the documentation).  I also would like 
to set even lower prio on certain computers. The Traffic Shaping/Control 
document lists that if SNAT is used, will NOPRIOHOSTSRC not have any 
effect, since the SNAT is done before the traffic shaping.

Any workarounds to get prio based on IP? (Will a second internal ethernet 
interface do the trick?)

Is NOPRIOHOSTDEST having effect? (I did not see that here in a quick test 



Shorewall 1.4.8
Linux kernel 2.4.23
