Event Forwarding Client IP address is in banned Country list

Hi everyone,

I'm running into an issue with an Event Forwarding CAPI integration and was wondering if anyone has encountered something similar.

We're consistently receiving a 403 response from the destination endpoint. The response message indicates that the client IP address is in the banned country list.

What's puzzling is that the requests are being sent from our Event Forwarding setup, and the vendor has stated that they do not believe the issue is on their side.

A few questions for the group:

• Have you seen a similar 403 error related to a banned-country or geo-restriction policy?
• Is there a way to determine the actual source IP being used by the Event Forwarding request?
• Could this be caused by proxying, cloud infrastructure, or regional routing that results in requests originating from an unexpected location?
• Were there any configuration changes or allowlisting steps required to resolve it?

Any insights, troubleshooting tips, or similar experiences would be greatly appreciated.

Thanks in advance!
