I've installed on Windows Server and it seems to be ok.
i've tried to install Secure gateway on the same server without issue.
Is it possible to install GMS and the secure gateway on the same server?
For my situation, my GMS server is already on DMZ so i think it's not necessary.

i've got another question, is it possible to connect other PO on the same GMS as i've got in all 4 PO.
