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:

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.

   

3. Click Edit to display Basic Settings for the VPN Virtual Server, and then verify the state of the DTLS setting.

   

4. Click More to display additional configuration option.

   

5. Select DTLS to provide communications security for datagram protocols. Click OK. The Basic Settings area for the VPN Virtual Server shows that the DTLS flag is set to True.

   

6. Reopen the Server Certificate Binding screen and click the plus icon (+) to bind the certificate-key pair.

   

7. Next to the certificate-key pair that you just bound, click Select.

   

8. Save the changes to the server-certificate binding.

9. When the certificate key pair appears, click Bind.
