OT but do people prevent direct access to the upstream servers (i.e. only allow the downstream proxy to make any queries) and if yes, how ?

  By having them only listen on the local network (or localhost).

  There are several ways to achieve that: 1. Listen on UNIX socket only 2. Bind TCP socket to localhost only 3. Bind TCP socket and port, cut off connections at firewall level
