I have a Heroku app (heresy) and I would like that app to be the only app talking to a service I am running on DigitalOcean. Heroku apps change their IP so I don’t think I can do a static UFW rule. Aside from JWT auth on the application level, is there a networking-level thing I can do to ensure only the Heroku app can talk with the DO app?

Hi there,
I believe that you could use a Heroku Static IP service like QuotaGuard Shield, which should provide you with a load balanced set of static IP’s to route either inbound or outbound traffic through to your desired destination:

Hope that this helps!
