TCP and UDP ports used by the Code42 platform

Available in:

Applies to:

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.

Port forwarding
You can use port forwarding, also called port mapping, to avoid port conflicts and port restrictions within your Code42 environment and on other networks.
