Connect through a proxy server

Dec 13, 2013

Proxy servers are used to limit access to and from your network, and to handle connections between Receiver and your Citrix XenApp or Citrix XenDesktop deployment. Receiver supports the SOCKS protocol, along with the Secure Gateway and Citrix SSL Relay, the secure proxy protocol, and Windows NT Challenge/Response (NTLM) authentication.

The list of supported proxy types is restricted by the contents of Trusted_Regions.ini and Untrusted_Regions.ini to the Auto, None, and Wpad types. If you need to use the SOCKS, Secure or Script types, edit those files to add the additional types to the permitted list.

Note: To ensure a secure connection, enable TLS/SSL.

Connect through a secure proxy server

Configuring connections to use the secure proxy protocol also enables support for Windows NT Challenge/Response (NTLM) authentication. If this protocol is available, it is detected and used at run time without any additional configuration.

Important: NTLM support requires that the OpenSSL library, libcrypto.so, is installed on the user device. This library is often included in Linux distributions, but can be downloaded from http://www.openssl.org/ if required.
