Is there a problem with using a free plan in company?

Hello
For clients who access services over the internet through a dynamic IP, but for a connection to a DB within a business environment (this is not directly over the internet like other applications), can the free version of Pritunl be used to provide this connectivity?
Looking at the pritunl/LICENSE link in master · pritunl/pritunl · GitHub, reading the license terms, I was confused about the use of the free version, whether or not it is possible to use it in this format.

More specifically in this excerpt
Non-Commercial

The license applies with or without a subscription. Commercial use would be requiring users to pay to use the software. It is unrelated to if the software is used in a business or corporate environment, the license does not prevent that usage.
