Real IP when dufs is behind proxy

Sorry if this has been asked already but I searched and didn't find (also looked in the source) Is there a way to get the dufs log to show the "real" IP of the client when behind a reverse proxy like [Cloudflare tunnel](https://developers.cloudflare.com/fundamentals/reference/http-headers/) or [Tailscale funnel](https://tailscale.com/docs/features/tailscale-funnel)? E.g. any support for showing `CF-Connecting-IP`, `True-Client-IP`, or `X-Forwarded-For` headers?
