Lots of people are using stacking. What's supposed to not work with it?

We've used the TNT exclusively to handle our primarily-Macintosh user 
base for years, over many code versions. Nothing ever broke Mac 
clients that I can recall, and I think I'd remember. I don't think 
the code vesion per se is your problem, but rather a setting that may 
have changed with a code upgrade.

I don't see any reason why you'd need to hard-code a default gateway 
with Mac clients, although you do need to hard-code DNS entries.

HTH.
