Do I need to open remote MySQL on my server to all IP addresses if connecting to a shinyapp.io app?

Hi

Do I need to open remote MySQL on my server to all IP addresses if connecting to a shinyapps.io app? Or is it possible to just allow one or a series? Current advice I have is that the only way to connect remotely from a hosted shinyapps.io app and a remote DB is to open remote mysql to all ip's. Can you confirm if this is correct please?

TIA,
Chris

No, not necessarily. Here you can find the IPs you need to white list.
