In almost every Parallels RAS project, the same question comes up early in discussions with network and security teams.
Which ports need to be open in the firewall?
The official Parallels documentation is comprehensive, but the information is spread across multiple pages and can be difficult to translate into concrete firewall rules.
In practice, project teams need to produce a clear flow matrix specifying:
- the source
- the destination
- the protocol
- the ports
- and the conditions of use
That’s exactly why I built the Firewall Rule Generator, available on RAS Insider.
The tool automatically generates the network flow matrix for a given Parallels RAS architecture.

For engineers working on-site or in environments without Internet access, the firewall flow matrix is available as an Excel file — ready to use, no browser required. The ZIP contains both the French and English versions.
