Hi
In lab 2 part 2 question 6, is the UDP packet we are talking about the one
- outgoing towards the internet
- incoming from the internet
?
Thanks
Hello,
The question mentions "forward incoming replies back to it", "it" being h2. So it is traffic incoming from the internet. The challenge with NATs is to know which of each incoming packet belongs to which host, whereas the destination of outgoing packets is trivial for the NAT.
