Citrix has recently announced the public beta of a new cloud feature called NetScaler Gateway services. This feature is a Windows based NetScaler solution which allows remote access to a Citrix environment using the windows server that has the cloud connector component installed.
When setting up Citrix Cloud Apps services you need to install a Citrix Cloud Connector which can only be installed on a Windows Server 2012 R2 server. With the new offering, which can be enabled within the Citrix cloud management console
Next time the cloud connector calls back to the cloud service it will detect that this feature is enabled and download and install it. This will essentially use the cloud connector server as an NetScaler Gateway, but do not worry! it does not require any chances to the server and it does not connect automatically back to clients who connect to it.
I configured my Azure Resource Manager environment with this service to see what was going on in the back!
