Menu path: Setup > Sessions > Citrix XenDesktop/XenApp > HDX/ICA Global > Firewall

In this area, you can configure the following firewall settings:

Use alternate address: Define a proxy or secure gateway server as an alternate address for connections via a firewall. Note the tool tips regarding the individual configuration parameters.

SOCKS / Secure proxy: Select the default proxy settings here or define the settings yourself.

Proxy type: If you use Secure (HTTPS), SSL/TLS or 128-bit encryption must be enabled in order for a secure connection to be established.

Secure Gateway (relay mode): If you would like to use a Citrix Secure Gateway in relay mode, you must give the full domain name – the IP address is not sufficient in this case.

After enabling the alternative address, add the server to the address list under Sessions > Citrix XenDesktop/XenApp > HDX/ICA Global > Server Location.
