Congrats on the new release! I have an AWS HF instance forwarding to on-premise indexers. Is this model supported? I didn't see mention of this model being explicitly supported or not supported and since the product was new, I wondered if this was a documentation oversight.
This is not a "supported" architecture, in the sense that it has not been tested as part of our release test pipeline with AWS. However, if you have an SSL cert, signed by a valid cert authority, on the heavy forwarder, then in theory there is nothing to prevent this from working.
