[MapProxy] Problems configuring MapProxy to serve WMS layer

[Jorge Arévalo]

Hello,

I'm having problem to make MapProxy render a Mapserver WMS layer. My
configuration file looks like this:

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

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

sources:
  my_wms_source:
    type:wms
    req:
      url: http://mydomain/cgi-bin/mapserv?
      layers: mylayer_in_mapserver
      map: /path/to/my/mapfile.map


Direct queries to mapserver works fine. So, a query like this works:

http://mydomain/cgi-bin/mapserv?styles=&map=/path/to/my/mapfile.map&format=image/png&width=800&height=600&bbox=-18.4267,27.3264,-13.0047,29.5457&layers=mylayer_in_mapserver&service=WMS&request=GetMap&srs=EPSG:4326&version=1.1.1

The key, I think, is in the bounding box. If I deploy MapProxy with
debug activated and try to see my WMS source through the demo app,
queries like these are raised:

http://mydomain/cgi-bin/mapserv?styles=&map=map=/path/to/my/mapfile.map&format=image%2Fpng&width=800&height=600&bbox=-506.77734375,
-266.8359375,370.01953125,190.1953125&layers=mylayer_in_mapserver&service=WMS&request=GetMap&srs=EPSG:4326&version=1.1.1

And that query doesn't work, because the bounding box is in a
different coordinate system (I guess epsg:3785).

How could I control that? The bbox used for WMS queries. I've tried
with 'srs' parameter in wms option of 'services' section, but it
doesn't work. Any clues?

Thanks in advance, and best regards
