MapProxy only advertises EPSG:4326 BBOX since most clients can reproject that and a list with all configured SRS would become quite large. But it might be a good feature to have more that one SRS as an option.

If I see it correctly, then this request is from your client. So it shouldn't be an issue of MapProxy.

> So, some wrong or forgotten parameter somewhere in the MapProxy configuration files (most probably in the mapproxy.yaml) is sort of forcing the usage of EPSG:4326 and consequently leading to what seems to us as an unwanted "reprojection" from EPSG:4326 to EPSG:4326 with the parameters of the reprojection from EPSG:2398 to EPSG:4326. 

Maybe, I can't tell you that without any configuration. :)

Oliver
