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.

Non-standard ports, meaning any port other than 443 and 80, are always bound to your local network and never connect to a remote cloud system.

Add the following websites to the allowlist on every machine that runs a Talend module.

Port information

  • Port: a TCP/IP port or a range of ports.
  • Active: Active for a standard installation of the product (Standard Installation is defined here as Server or Client installation using Talend Installer with the default values provided in the Installer User Interface).
  • 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.
  • Note: anything which is important to mention additionally.
