It is impossible to answer your questions because -

  1. inaccurate information
  2. it is not clear what configuration we are using. The basis for everything is default rules or some other configuration.
  3. your description in general is one big mix
  4. what does the circuit diagram look like (drawing or paint, whatever)
  5. latest version 7.14?
  6. something can be said more precisely if the configuration is visible (without security/personal information)
