A very good day to you Sir !
I hope your day is going Great !

May I please kindly ask - How can I add these configurations to my RouterBoard 850GX2 Router :

  1. Block all inbound traffic where the source address is from your internal networks.

  2. Block all outbound traffic where the source address isn’t from your internal networks.

  3. Block all inbound and outbound traffic where the source or destination addresses are from the private address ranges.

  4. Block all source-routed packets.

  5. Block all broadcast packets, including directed broadcasts. Broadcasts are useful inside a network,

  6. Block all packet fragments. Fragrouter is an old but wonderful tool, imminently useful for evading network intrusion detection.

Thank you very much for your time and kind help !

Warm Regards as always

The default config already has such rules.

Thank you for the quick reply …

Where can I go in the router to verify that these rules are indeed configured into my router ?

Thank you

The same command hierarchy is applied in the Winbox and Webfig GUIs menus.

Dave, I am afraid… to say, but this is less than a beginner section question.
Read first, try it out, and then ask if it is not working.
