Hey there, and thanks in advance to everyone who’s willing to help 
I have the plugin “bouncer” installed to grant access only to special sites for viewer and editors. that works.
also i followed the cookbook for file-firewalls: Protecting files | Kirby CMS
and got working, that if i upload any file the file URL is only readable when logged in cause you never get the original file path.
perfect and thanks to @texnixe
this works in my blueprint when:
files:
            type: files
            template: protected
Now i want ALL file uploads on this pages with this blueprint to be “secured”. how can i get the route template working for parts like:
fields:
                      bezeichnung:
                        label: Bezeichnung
                        type: text
                      beschreibung:
                        label: Beschreibung
                        type: textarea
                      bild:
                        label: Bild
                        type: files
or
type: layout
                layouts:
                  - "1/1"
                  - "1/2, 1/2"
                  - "1/4, 1/4, 1/4, 1/4"
                  - "1/3, 2/3"
                  - "2/3, 1/3"
                  - "1/3, 1/3, 1/3"
                fieldsets:
                  - heading
                  - text
                  - list
                  - image
                  - gallery
                  - video
                  - code
                  - markdown
                  - button
                settings:
                  fields:
                    class:
                      type: text
                      width: 1/2
                    id:
                      type: text
                      width: 1/2
                    image:
                      label: Background image
                      type: files
                      fields:
I tried to add “template: protected” again but i does not work.
Perhaps someone can give me a hint…
