I'm about to deploy a GWIA setup on my groupwise system. Now, I want to put GWIA agent on my network's DMZ, so far so good. Now the question: How should I deploy the GWIA domain? A new tree just for DMZ, making GWIA an isolated groupwise system from my "non-DMZ" system, then setting up a external groupwise system on my internal system (does this even work?). Or just make the GWIA part of the existing tree, on it's own domain of course, making it a simplier setup?
Any advice?

Thanks in advance.
