NetScaler Gateway requires a Platform license. The Platform license allows an unlimited amount of connections to XenApp, XenDesktop, or StoreFront by using ICA proxy. To allow VPN connections to the network from the NetScaler Gateway Plug-in, a SmartAccess logon point, or Worx Home, WorxWeb, or WorxMail, you must also add a Universal license. NetScaler Gateway VPX comes with the Platform license.
The Platform license is supported on the following NetScaler Gateway versions:
The Platform license allows unlimited user connections to published applications on XenApp or virtual desktops from XenDesktop. Connections by using Citrix Receiver do not use a NetScaler Gateway Universal license. These connections only need the Platform license. The Platform license is delivered electronically with all new NetScaler Gateway orders, whether physical or virtual. If you already own an appliance covered by a warranty or maintenance agreement, you can obtain the Platform license from the Citrix web site.
The Universal license limits the number of concurrent user sessions to the number of licenses you purchase.
The Universal license supports the following features:
If you purchase 100 licenses, you can have 100 concurrent sessions at any time. When a user ends a session, that license is released for the next user. A user who logs on to NetScaler Gateway from more than one computer occupies a license for each session.
If all licenses are occupied, no additional connections can be opened until a user ends a session or you terminate the session. When a connection is closed, the license is released and can be used for a new user.
The Express license is used with the NetScaler VPX and allows for up to five concurrent user connections by using Receiver or the NetScaler Gateway Plug-in. The Express license is available for the VPX appliance and expires after one year. Users can connect to either Basic or SmartAccess virtual servers.
After you download NetScaler VPX, from the NetScaler VPX web site, you acquire a license key, and then you activate and download your license file. You will need to provide the host name of your Citrix License Server or the host name of the NetScaler appliance.
