Configuring NetScaler Gateway to Support Enlightened Data Transport

If you use Enlightened Data Transport (EDT), Datagram Transport Layer Security (DTLS) must be enabled to encrypt the UDP connection used by EDT. The DTLS parameter must be enabled at the Gateway VPN virtual-server level, and XenApp and XenDesktop components must be correctly upgraded and configured to achieve encrypted traffic between the Gateway VPN virtual server and the user device.

The following scenarios are supported:

Scenario EDT support
NetScaler Gateway Yes
NetScaler Gateway with High Availability (HA) Yes
NetScaler Gateway with High Availability (HA) optimization Yes
NetScaler with Unified Gateway Yes
NetScaler Gateway with GSLB Yes
NetScaler Gateway with Cluster Yes
Citrix Receiver to NetScaler Gateway DTLS encryption Yes
Dual Secure Ticket Authority (STA) on NetScaler Gateway Yes
NetScaler Gateway ICA session timeout Yes
NetScaler Gateway Multi-Stream ICA Yes
NetScaler Gateway session reliability (Port 2598) Yes
NetScaler Gateway Double-Hop Yes
NetScaler to VDA DTLS encryption No
HDX Insight No
NetScaler Gateway in IPv6 mode No
NetScaler Gateway SOCKS (Port 1494) No
NetScaler pure LAN proxy No

Note: EDT support for NetScaler Gateway is available for port 2598 and not for port 1494.

To configure NetScaler Gateway to support EDT:

  1. Deploy and configure NetScaler Gateway to communicate with StoreFront and authenticate users for XenApp and XenDesktop.

  2. On the Configuration tab in the NetScaler GUI, expand NetScaler Gateway and select Virtual Servers.
