Installation and Upgrade

The following tables list the most important TCP/IP ports the Talend products use.

You need to make sure that your firewall configuration is compatible with these ports or change the default ports where needed.

Add the following websites to the allowlist on every machine that runs a Talend module:
URL Port Usage 443 For downloading additional packages such as Bonita BPM Integration, Talend Metadata Bridge and upgrades from Talend Studio tools 443 For downloading libraries in Talend Studio (mainly for components) 443 For testing and sending usage statistics from Talend Studio 443 For using Talend Exchange in Talend Studio and for users actions such as clicking on forum links 443 For user actions, such as clicking on Community links, etc. 443 For user actions, such as clicking on help links, etc.
Note: If your deployment depends on other third-party software, you may need to add other URLs to your allowlist. Talend recommends adding to the allowlist all hostnames that have dynamic IP addresses.

In this table:

  • Port: a TCP/IP port or a range of ports.

  • Direction: In (Inbound) and Out (Outbound) refer to the direction of requests between a port and the service (or CFX route) communicating with it. For example, if a service is listening for HTTP requests on port 9080, then it is an inbound port because other services are performing requests on it. However, if the service calls another service on a given port, then it is an outbound port.

  • Usage: which part of the Product component uses this port (for example 1099 is used by the JMX Monitoring component of Talend Runtime).

  • Configuration file: the file or location where the value can be changed.
