I currently use traffic shaping and NAT with m0n0wall. I am currently
using 1.23b1, because it was causing problems when multiple computers
were using the internet. For one on my wife's laptop it would not even
connect to the apple software update.
 I know that the beta website says "a rather intrusive kernel patch
was required to make concurrent traffic shaping + NAT on the   WAN
interface possible; if you rely on this feature, please test it well
and report any problems"
 What kind of test would you recommend so that this can be improved?

 Chris
