Which components do I need to install in a DMZ?

Starting with DocuWare 6.7 the web components connect directly to the database server. Therefore it is not recommended and not supported to install DocuWare web components in a DMZ.
The web components should be installed within the LAN only. The web server in the DMZ acts as a reverse proxy then. All requests will be redirected e.g. via ARR (Application Request Routing) to the appropriate internal web server.

You'll find a description how to setup up a web server as a reverse proxy with ARR here:

In section "Configuring Rules for the Reverse Proxy" you need to redirect all requests to http://.../DocuWare/ to your internal DocuWare web server.
