It is true that we cannot ping a private IP address on the internet, and that is the concept, but when we create a network in the Cisco Packet Tracer, what is the reason that we are able to ping a private IP from one network to another private IP in another network?
I made a network as shown:
The serial interface represents a WAN, e.g. the Internet (if i am not wrong). I configured RIP on both the routers. Now, the serial interface can actually be a mesh of routers (configured with RIP) from where my packets can travel. So, is it true that any intermediate routers in the WAN can also ping here?
That is, if my routers are at two branches of my organization in two places, is it possible that any intermediate person can gain access to my internal network? I know that the answer has to be NO, but then why/why not?
I am really confused.
