3.2 Ports
This section lists the different ports that should be opened for communication between the different
Acronis components inside the network as well as traffic to the outside. These are same ports as
used in the diagram above, but presented in a list by component.
Note that all communication between the many services of a single component are also done
through network connections. These services listen exclusively on localhost and the ports are not
listed here because nothing needs to be opened in the firewall or otherwise changed in your
network.
Though these internal ports do not affect traffic, they can create a conflict if another application is listening on
the same port. You can usually change the internal port used by Acronis services in the .json configuration file
for the service found in its directory in c:\Program Files\Acronis\[service_name]\[service_name].json
Management Server
The following ports should always be opened on the Management Server for incoming connections
from different components:
 TCP 9877 (API gateway)
 TCP 7780 (for communication with the agents)
 9850 (ASYNC IPC)
The following ports are optional if you want to access the Management Server from the remote
command line:
 TCP 9851
