Between the appliance and a protected machine

In Windows, these ports are opened automatically during installation of the DR backup agent.

Port Protocol Direction Purpose
9101, 9102, 9103, 9104, 9105 TCP Appliance to the client machine Basic appliance communication
9102 UDP Client machine to the appliance Appliance auto-discovery
139, 445 TCP Client machine to the appliance DR image backup (Samba ports)
135, 137, 138 UDP Client machine to appliance DR image backup (Samba ports)
80 TCP Client machine to appliance Diagnostic information

In a Unix-like operating system, you also have to open the following ports:
