In my case, it was enough for ADH to be able to roughly classify by CIDR, so I limited the CDN server address to which each client connects to only the gateway address.

If you really have to do a complete client address classification here,
A complete two-stage configuration without loopback will maybe hurt performance, so I think easier to have an API for intermediate processing of CDN requests (irresponsible remarks🥴)
