Gateway Port Reference
Port Reference
An Ignition server uses many ports to manage information between itself and other Ignition servers, OPC servers, devices, and other services such as SMTP and ERP servers. The following table describes the default ports an Ignition server may use for communication. Most are configurable and some of these ports may be on a computer other than the one Ignition is installed on (that is, if MySQL is installed on a different computer, the Ignition server will not be using port 3306). This is not a complete list of TCP ports, and there are a few UDP and broadcast ports in the list. Ignition will potentially use other ports if you are connecting to additional services or devices. Setting ports may be possible for some of the following, but will depend on their respective software.
Ignition Ports
| Port | Operation | Protocol | Configurable | Description |
|---|---|---|---|---|
| 8088 | Listening | tcp | Yes | Default port setting to access the Ignition Gateway. Also the non SSL port for the Gateway Network. |
| 8043 | Listening | tcp | Yes | Default SSL port setting to access the Ignition Gateway |
| 8060 | Listening | tcp | Yes | Default SSL port setting for the Gateway Network (metroSSLPort in the Gateway XML file) |
| 4096 | Listening | tcp | Yes | Default port for Ignition OPC-UA server |
| 4446 | Listening | udp/broadcast | Yes | Default receive port for multicast messages that makes the Gateway discoverable on a local network. |
| 5500 | Listening | tcp | Yes | Default port for OPC browse of external Tags. |
| 6501 | Listening | tcp | No | Server fallback port |
| 8750 | Listening | tcp | No | Port used for Redundancy/Network Configuration |

| 4445 | Outgoing | udp/broadcast | Yes | Default send port for multicast messages that makes the Gateway discoverable on a local network. |
| 17341 | Outgoing | tcp | No | Send port for SMS with Alarming |
| 1883 | variable | tcp | No | MQTT Unencrypted. Outgoing port if using an external MQTT broker, Listen port on Ignition if using the Distributor module |
| 8883 | variable | tcp | No | MQTT SSL/TLS. Outgoing port if using an external MQTT broker, Listen port on Ignition if using the Distributor module |
