# Gateway Port Reference

> The following table describes the default ports an Ignition server may use for communication.

## 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  | Direction | Protocol  | Configurable | Description  |
|---|---|---|---|---|
|80|Incoming|TCP|Yes|Default port setting to access the Ignition Gateway when using **Ignition Cloud Edition**.|
|443|Incoming|TCP|Yes|Default SSL port setting to access the Ignition Gateway when using **Ignition Cloud Edition**.|
|1883|Incoming|TCP|No|**MQTT** Unencrypted. Outgoing port if using an external MQTT broker, Listen port on Ignition if using the Distributor module.|
|4096|Incoming|TCP|Yes|Legacy port for **Ignition OPC UA** server. Versions 7.9 and prior used this port for UA server communications. When upgrading from Ignition 7 to 8+, the legacy port will initially be used.|
|4445|Outgoing|UDP/broadcast|Yes|Default send port for **multicast messages** that makes the Gateway discoverable on a local network.|
|4446|Incoming|UDP/broadcast|Yes|Default receive port for **multicast messages** that makes the Gateway discoverable on a local network.|
|6501|Incoming|TCP|No|The port utilized by Vision's [Local Client Fallback](ignition-modules\vision\local-client-fallback\local-client-fallback.md) feature. |
|8043|Incoming|TCP|Yes|Default SSL port setting to access the **Ignition Gateway**.|
|8060|Incoming|TCP|Yes|Default SSL port setting for the **Gateway Network** (metroSSLPort in the Gateway XML file).|
|8088|Incoming|TCP|Yes|Default port setting to access the **Ignition Gateway**. Also the non SSL port for the Gateway Network.|
|8883|Incoming|TCP|No|**MQTT** SSL/TLS. Outgoing port if using an external MQTT broker, Listen port on Ignition if using the Distributor module.|
|17342|Incoming|UDP|No|Receive Port for **SMS** with Alarming.|
|17341|Outgoing|UDP|No|Send port for **SMS** with Alarming.|
|62541|Incoming|TCP|Yes|Default port for **Ignition OPC UA** server.|

### Other Common Software/Hardware Ports

:::caution
The information listed below has been included for user convenience when attempting to access specific services. All details should be verified by the relevant third party documentation, which may also identify other configuration settings not mentioned on this page that need to be modified to make the listed ports accessible.
