KB351930081: Pack Proof - Which ports are used by the Fiery Command Workstation

Question

Fiery Command Workstation can't connect with the Proof Server installed on another system. Which ports must be open for this connection?

Answer

The Fiery Command Workstation uses the PORTs 50005-50025 for connection.
Access through PORT: 50007 has been found in multiple instances to be the root cause of a failing connection with the Proof Server.
Configuring the local group policies / network security protocol / firewall to allow the pass-through connection has been found to resolve this issue.

When a connection is still not possible then check this KB for other recommendations regarding anti-virus and firewall settings:
