Q52 / 100
What is network address translation and what problems does it create?
Correct! Well done.
Incorrect.
The correct answer is B) NAT breaks end-to-end connectivity (peers can't initiate connections to NATed devices), complicates protocols embedding IPs in payloads, and requires hole punching for P2P
B
Correct Answer
NAT breaks end-to-end connectivity (peers can't initiate connections to NATed devices), complicates protocols embedding IPs in payloads, and requires hole punching for P2P
Explanation
NAT breaks the internet's end-to-end model. Protocols like FTP (PORT command embeds IP) and SIP/VoIP need ALGs. P2P requires NAT traversal (STUN/TURN/ICE) for hole punching.
