Required Ports for WSO2 IoT Server

The following ports need to be opened for WSO2 IoT Server, and Android and iOS devices so that it can connect to Google Cloud Messaging (GCM)/Firebase Cloud Messaging (FCM) and APNS (Apple Push Notification Service), and enroll to WSO2 IoT Server.

Default ports

8243	HTTPS gateway port.
9443	HTTPS port for the core profile.
8280	HTTP gateway port.
9763	HTTP port for the core profile.
1886	Default MQTT port.
9445	HTTPS port for the analytics profile.
9765	HTTP port for the analytics profile.
1039	HTTP port for the analytics profile

Ports required for mobile devices to communicate with the server and the respective notification servers.

	Android
5228 5229 5230	The ports to open are 5228, 5229 and 5230. Google Cloud Messaging (GCM) and Firebase Cloud Messaging (FCM) typically only use 5228, but it sometimes uses 5229 and 5230. GCM/FCM does not provide specific IPs, so it is recommended to allow the firewall to accept outgoing connections to all IP addresses contained in the IP blocks listed in Google's ASN of 15169.
	iOS
5223	Transmission Control Protocol (TCP) port used by devices to communicate to APNs servers.
2195	TCP port used to send notifications to APNs.
2196	TCP port used by the APNs feedback service
443	TCP port used as a fallback on Wi-Fi, only when devices are unable to communicate to APNs on port 5223 The APNs servers use load balancing. The devices will not always connect to the same public IP address for notifications. The entire 17.0.0.0/8 address block is assigned to Apple, so it is best to allow this range in the firewall settings.
