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.
Tommy,
The current version of Xeams does not look for these headers and therefore, will always think the end-user is connection from the same IP. We can certainly add this in the next release of Xeams.
