9.1. Setting up ICA connections

This section focuses on describing the ICA-specific details of connection configuration. For a detailed description on configuring connections, see Chapter 7, General connection settings.


If the clients are accessing a remote application or desktop that is shared for Anonymous users (that is, the Users properties of the application is set to Allow anonymous users in the Citrix Delivery Services Console), the actual remote session will be running under an Anonymous account name (for example, Anon001, Anon002, and so on), not under the username used to access the remote server. Therefore, you need to enable usermapping to the Anon* usernames.

To accomplish this, create a usermapping policy and set the Username on the server option to Anon*, and the Groups option to *, then use this usermapping policy in your ICA connections. For details on using usermapping policies, see Procedure 18.1, Configuring usermapping policies.

Reliable connection is also known as Common Gateway Protocol (CGP). It attempts to reconnect to the server in case of a network failure. To use this feature, enable Reliable and enter the default port in the Port field in the upper right corner.

Enable Act as SOCKS proxy to configure the client to use PSM as a SOCKS proxy. If you have enabled this option, you can select Inband destination selection as Target. Enter the IP address or the IP address/Prefix of the brokers (Citrix XML Brokers) used by the client in this connection policy into the Address field. It is also recommended to enable access to the brokers on port 443, as the clients usually try to access the broker using this port first. Disabling port 443 will cause a denied connection to appear on the PSM Search interface for every connection attempt (but the clients will be able to connect the server).


PSM does not audit or monitor the traffic between the brokers and the clients in any way, and are not listed on the PSM search interface. Only the connections between the clients and the actual servers are audited.


If PSM is acting as a SOCKS proxy and a client attempts to access a server that it is not permitted to access according to the configuration of PSM, PSM will deny the connection. However, the Citrix client application will automatically attempt to connect the server directly without using a proxy and will succeed if the server is directly accessible from the client. Ensure that your firewalls are configured properly to prevent such connections, as these direct connections cannot be audited by PSM.


When enabling Reliable connection or Act as SOCKS proxy the first time, a warning is displayed suggesting the default port to be used based on the specific settings. Also, read the tooltips on these options as they contain up-to-date information about the default port numbers.
