   I'm not sure what you're trying to do here...

   If you want to use the Mac Mini as a (NAT) router then it won't work. I 
   looked into this fairly extensively - admittedly under Linux rather 
   than Mac OS X, but it shouldn't make any difference - trying to route 
   through a single physical interface causes packet collisions and 
   slowdowns & all manner of Bad Things. It might work _extremely slowly_

It really depends on the load and various network speeds involved.

If you've got a DSL line that tops out at a megabit and the Mini is
hooked up at 100 Mbps, I don't see a problem.

It also depends on the application load.

The best thing is to be much more clear and detailed in your question.
