Firewall Ports

During server installations, the installation setup detects whether there is a firewall on the computer. You must either disable the firewall or configure it to allow communication with remote clients.

The following is a list of the default inbound TCP ports you must open on the server computer to allow communication:
  • 8447
  • 8012
  • 8111
  • 8112
  • 8020
  • 8201
  • 8202
  • 8203
  • 8204
Important: As of Workflow version 2.6, the default port for REST services hosted by Workflow is changed from 8444 to 8447. The REST service port is NOT changed during upgrade of existing installations and remains 8444.

GE Web HMI and GE Workflow do not work together if installed on the same machine as both applications require the use of port 8444. You must change the port number in your Workflow server information in Web HMI. If no port information is provided, the default is used. For information about resolution of port conflicts, see Resolve Port conflicts between prior Workflow installations and Web HMI. For existing Workflow installations prior to 2.6, Workflow and Web HMI ports are both set to 8444, making applications installed on the same machine incompatible.
