This tutorial only applies to Cloud Computers that were built with a Private IP address. If you built the computer with a Public IP address, all ports are open by default and port forwarding is not possible or required.
To forward a port to your Cloud Computer, click Actions — Manage computer from your Cloud dashboard.
Go to the Networking tab and click Add new port forward
Enter the public port you want to forward and click OK
A random public port will be generated and forwarded to the Cloud Computer. You can remove the port forward by clicking Actions — Remove
