How can I configure ports and firewalls following download and login to the Excel Add-in to connect and retrieve reference data from Fastmarkets?

The Fastmarkets Excel Add-in uses several APIs to retrieve its data. If you wish to configure your firewall using domain names, please whitelist the following: 

• api.fastmarkets.com
• auth.fastmarkets.com
• downloads.fastmarkets.com

Fastmarkets uses Imperva to manage its IP addresses. If you wish to restrict by IP range, please refer to this document for a complete list: https://docs.imperva.com/howto/c85245b7
