* This functionality has not been tested and is not supported for use with ColdFusion MX.
** If port 2901 is in use, the next available port is used; the webserver connector installer can auto-discover a port value between 2900-3000 for the connection.
Note: This table does not describe ports used by external resources such as databases, mail, and LDAP servers.
Additional port information
In order to provide functionality such as mail and FTP connections within applications, ColdFusion MX will open other ports as needed. These ports are in addition to the well-known ports that those TCP/IP protocols open. They are assigned by the operating system at runtime (ephemeral ports) and are usually recognizable by their high number (for example 39738), although the available range can vary based on specific configuration changes that can be made to the operating system to affect the range allowed.
