The source is the ViennaGIS multi-porpose map (https://www.wien.gv.at/stadtplan/). The capabilities document is here: http://maps.wien.gv.at/wmts/1.0.0/WMTSCapabilities.xml. I followed the instructions at http://lists.osgeo.org/pipermail/mapproxy/2013-August/001674.html to calculate the right scale factors and generally followed http://mapproxy.org/docs/nightly/configuration_examples.html#create-wms-from-existing-tile-server for the basic configuration (by the way, I’m using the 1.7.0a nightly build).

google3857 suggests that the tiles are in the Google/OSM webmercator grid. Have you tried GLOBAL_WEBMERCATOR?
Setting the BBOX for a grid changes how the tile coordinates are calculated. You can use the coverage feature to limit the extent of the service.
