If you have firewall protection on any machine on which you will install Denali, you need to either temporarily disable the firewall or add exceptions before you begin the installation. You can do this through your Control Panel. After installation is complete, you can reactivate your firewall protection. Keep in mind that the information we present is based on Windows default settings and does not take into account any modifications you might have already made.

If you choose to add exceptions, depending on how you plan to set up your network configuration, you need to make sure the machine(s) that will have the various components are set as follows:

For more information on these different components, refer to Overview of Denali Structure. For more information on Windows firewall exceptions, refer to the Windows documentation. If you have a firewall other than Windows, refer to the documentation that came with that program.

When you are prompted for a port number, you can choose any naming convention, but the recommended port numbers for use with Denali are listed in the table below.

If you are prompted to select TCP or UDP, it’s important to note that Denali only supports TCP communication.

Once you finish adding required exceptions, close the Windows Firewall window and continue setting up your machine(s) for the Denali installation or begin the installation process.
