Overview
The Code42 server, the Code42 app, and other products in your Code42 environment use certain network ports to function normally. If you have network connectivity issues with Code42 for Enterprise, verify that your firewall rules permit traffic over these ports.
Code42 server network ports
Inbound ports
The following table lists the default Code42 server ports. It is best practice to deny inbound traffic at the firewall for any ports not needed by the Code42 configuration.
You can use port forwarding, also called port mapping, to avoid port conflicts and port restrictions within your Code42 environment and on other networks.

* Code42 server version 5.3 introduced TLS encryption; servers listen at both 4282 and 4287. In version 5.4, TLS is enabled by default. See Enabling TLS Messaging.
