I try to cascade WMS that is published by different mapping server(Bentley GeoWebPublisher) in epsg:2320 to WMS service as epsg:4326 using GeoServer.
I selected epsg:2320 as "Native SRS". I tried epsg:2320 for "Declared SRS" and requesting the layer from client (to say QGIS and Leaflet) with epsg:4326 hoping that GeoServer will make necessary on the fly transformation based on the request's SRS code. I keep getting "Invalid SRS specified." As an alternative solution I tried to declare "Native SRS" as epsg:2320 and "Declared SRS" as 4326 with options "Force declared","Reproject from native". All alternatives resulted with same error-"Invalid srs specified."
Is it wrong to expect on the fly transformation from GeoServer?
As an additional information, source WMS is provided only as epsg:2320.
