Port Mapping

In environments with multi-user systems—such as Microsoft Terminal Server or Citrix environments—many users share the same IP address. In this case, the user-to-IP address mapping process requires knowledge of the source port of each client. To perform this type of mapping, you must install the Palo Alto Networks Terminal Services Agent on the Windows/Citrix terminal server itself to intermediate the assignment of source ports to the various user processes. For terminal servers that do not support the Terminal Services agent, such as Linux terminal servers, you can use the XML API to send user mapping information from login and logout events to User-ID. See Configure User Mapping for Terminal Server Users for configuration details.
