How to add and manage Floating IP addresses in mCloud

This article details how Floating IP addresses can be managed in the Cloud Dashboard as well as how port forwarding can be managed.

Floating IPs in mCloud refer to a public IP Address that can be attached and moved between multiple instances and does not require any reconfiguration to the underlying resources. There are a few ways that a Floating IP address can be deployed:

  • Completely Floating - Leave the IP completely detached from instances and configure it to forward specific ports only.

  • Associated - The floating IP is mapped 1:1 to a specified network port

Things to keep in mind while using Floating IP Addresses:

Method - Adding a Floating IP to a Project
