[MapProxy] Problems configuring MapProxy to serve WMS layer

[Jorge Arévalo]

Hi,

Many thanks for the link. It helped me to solve my problem. The
'supported_srs' option and a couple of things related with my network
configuration did the trick. I finally came with:

services:
  wms:
    srs: ['EPSG:3785', 'EPSG:4326', 'EPSG:23028']
    image_formats: ['image/jpg', 'image/png']

 layers:
  name: mylayer
  title: My layer
  sources: [my_cache]

caches:
  my_cache:
    grids: [GLOBAL_MERCATOR]
    sources: [my_wms_source]
    format: image/png
    request_format: image/png

 sources:
   my_wms_source:
   type:wms
   req:
     url: http://ip_of_my_mapserver_machine/cgi-bin/mapserv?
     layers: mylayer_in_mapserver
     map: /path/to/my/mapfile.map
  supported_srs:['EPSG:3785', 'EPSG:4326', 'EPSG:23028']


Best regards,
Jorge
