I have about 40 machines on my internal network and 4 Servers, so  
that won't be happening.  I know other appliances allow this, that's  
the only reason I'm trying to figure out a solution.  Thanks for the  
comment.  I hope I don't have to do something that drastic.

I had a similiar issue.  I just changed my internal network.  I had  
about 8 machines running and a ton of rules setup, but that was the  
least painful thing to do.
