There is no difference in the installer for Xeams Community and Enterprise Edition. It will run as if you have purchased the Enterprise Edition for the first 30 days. It will then get converted to Community Edition unless a license is purchased.
I opened up that port for my qnap, but it's still refusing connection. I can run it but I can't get into the admin to set it up. Also it says JRE QPKG not installed...
