TCP 22: Traffic is encrypted by using the SSH protocol.
TCP 445: Traffic encryption depends on the File and
Printer Sharing options in Windows
TCP 9876: By default, traffic is encrypted. Encryption is
configured through the Acronis administrative template.
TCP 25001: Traffic itself isn’t encrypted. But all user
names and passwords are sent encrypted.
Encryption notes:
Installation packages (.msi files): Contain
components being installed
Acroinst.exe: Manages the installation process
Msi_setup.exe: Installs a component

: The arrow direction shows which component initiates a connection. The text shows the destination port. The source port is 1025–
5000 (Windows prior to Windows Vista), 49152–65535 (Windows Vista and later), or 32768–61000 (Linux and the virtual appliance).
The agent registers itself by using the specified network name or IP address of the management server. If the network name is
specified, the agent obtains the IP address either from the DNS server or from the hosts file (%SystemRoot%\system32\drivers\etc\
hosts in Windows or /etc/hosts in Linux). Adding the management server to this file helps when the agent is located on a different
subnet than the management server.
In a non-DNS environment, it is necessary to enable Network Discovery and File and Printer Sharing on the machine from where the
installation is performed (the management server or the management console). This requires additional TCP and UDP ports to be open.
