Hi,
at my company we recently started to use Power BI. We use an on-premise MySQL database, we'd like to get the data from.
I read that to get past our firewall and access the database from Power BI online, we would need to either whitelist the domain names or the Microsoft Azure IP ranges list. https://powerbi.microsoft.com/en-us/documentation/powerbi-gateway-enterprise/
Both ways aren't working for us. Whitelisting the domain names (mentioned in the link above) isn't possible since wildcards are not supported. Our IT admin told me that whitelisting the list of IP ranges also isn't possible, since we don't want to open up our database to such a big (and varying) list of IP ranges.
Is anyone aware of a way to allow Power BI online to get past the firewall of an on-premise database without having to whitelist such a big list of IP ranges?
(I'm neither a developer nor a database specialist. Please keep that in mind when phrasing an answer 
)
I appreciate every hint and help I can get, since I really want to make this work!
Thanks for your time!
Sebastian
