We are in the need of whitelisting AppBuilder (Firefly) infrastructure so that only requests coming from the IP Ranges it has would be allowed for communication with external systems it needs to connect.
For security purposes we need to whitelist inbound traffic to an external system, the inbound traffic is coming from AppBuilder so the error message we get is Timeout.
How can we know what IP AppBuilder is using to whitelist it and allow it to access our external system?.
