NetScaler Gateway as a Service

May 25, 2016

NetScaler Gateway provides users with secure, remote access to XenApp, XenDesktop, and XenMobile applications across a range of devices including laptops, desktops, thin clients, tablets, and smart phones.

NetScaler Gateway as a Service enables secure, remote access to XenApp and XenDesktop applications, without having to deploy NetScaler Gateway in the perimeter network (also known as a DMZ) or reconfigure your firewall. The entire infrastructure overhead of using NetScaler Gateway moves to the cloud, where the cloud service is hosted by Citrix.

You enable NetScaler Gateway as a Service using a check box. Once it has been enabled, users can access their VDAs from outside their network, as shown in the following diagram.

Enabling NetScaler Gateway as a Service

By default, NetScaler Gateway as a Service is disabled.

  2. Enable NetScaler Gateway.
  3. Choose Use cloud hosted Citrix NetScaler Gateway.

Known Issues

Be aware of the following limitations in the current service:

  • The service is currently enabled only for use with HDX traffic as part of the XenApp and XenDesktop Service. Other NetScaler Gateway functionality is not enabled.
  • The service is available on the eastern and western coasts of the United States, and in Europe. As HDX traffic travels through the service, users and/or XenApp or XenDesktop servers located outside those areas experience higher latency.
  • The Citrix Cloud Connector located within your Citrix Cloud resource locations communicates with Citrix-run cloud services over the Internet. Currently this communication channel does not support authentication at outbound proxies for access to the Internet.
  • All network traffic is protected by SSL, but to provide the NetScaler Gateway functionality, HDX traffic is present in memory in an unencrypted form.
  • To use the NetScaler Gateway Service, you must use StoreFront hosted within the Citrix Cloud.
