Software requirements for FLR proxy 

Before you deploy and activate the FLR proxy, ensure that following system requirements on the Hyper-V host are met for the proxy:

Ports and communication protocols for Druva

Druva communicates with your hosts to backup and restore data on your hosts. Druva talks to your Hyper-V host through ports and protocols that are secure for communication and transition of data.

Druva uses Transport Layer Security (TLS) protocol for establishing the connection and initiating communication between Druva components and your Hyper-V hosts.

The following diagram depicts the ports and communication protocols that are used by Druva for secure connection and communication during the backup and restore operations.
