I wonder if IP fragmentation would/could have any effect on the ability for a Nation State's (i.e., China, Russia, North Korea, ?, ???) firewall to prevent packets from entering/leaving a blocked country... Why or why not? In fact, now that I think about it... what happens if a TCP/IP connection is initiated from another country to a TCP/IP address inside of an outwardly blocked country? Would that act similar to a NAT punchthrough, but on a Nation-State's firewall? Think about it this way... let's take an arbitrary example, China... And let's suppose for the purposes of discussion that what the western Mainstream Media says about China's Internet is completely true -- that outgoing connections to the West from China -- are blocked. OK, but there still is Alibaba -- the equivalent of China's Amazon.com. Connections FROM the West (e-commerce connections, "we buy from you", "you are a merchant to us", etc., etc.) TO Alibaba.com (in China) -- are not blocked, and would NOT be blocked by the Chinese government! Why? Because anywhere there's trade -- if the trade is beneficial to the government in question (anyone heard of taxes, anyone? They benefit the government you know!) -- there will be internal political pressure NOT to prevent that trade from occurring! So let's say that a TCP/IP connection that looked like a legitimate e-commerce connection -- was initiated FROM the West, to an IP address in China for a legitimate Chinese e-commerce site... Now, couldn't that connection, once established (since it is, after all bi-directional) -- be used to send data outside of China? Yes! But to only one outside/external IP address! But what if that IP address on the Western side (being in a non-firewalled country) -- now could somehow route that data to any other IP address around the world? Sort of like a VPN -- but the connection is opened up from an INCOMING connection, not an outgoing one... Would that be the equivalent of NAT punchthrough -- for a Nation State's firewall? ? Before you answer, I'm guessing that there are Deep State bots (from all countries!) that will try to derail this conversation... That's a testament to "always think for yourself" (let logic be your guide!) -- stay away from so called "expert" opinions, especially one or two sentence "no it can't be done" or "it would never work" replies by fake posters with fake names from fake accounts! But, I guess we'll open up the floor to the AI powered agenda-driven bots... foreign and domestic! :-) Also, note that I don't suggest/condone that anyone actually do any of the above -- this discussion is theoretical in scope only!
