These are my first questions asked into this forum so could you please help me? These were asked during a job interview:
How does the ping work when we launch an ICMP echo request message from an internal LAN private IPv4 source address towards a public IPv4 destination address (example
22.214.171.124- Google server) without enabling the NAT/PAT protocol on our default/internal gateway router?
If the ping is unsuccessful (receiving the requested timed out/time exceeded) ICMP error type, which next-hop node will prevent forwarding the traffic (ICMP control) packets towards the Internet?
Which methods we should use in order to obtain a successful echo reply ping?
I have thought of a possible answer, which I will share with you after the response in order to see if it's valid or not.
