Hello,
For the question in macSols slide 60, why is the answer A wrong? Because I thought that if Bob is behind a NAT then his MAC address will not appear and Lisa will not be able to access EPFL.
Thank you in advance,
Amine
If Bart is behind a NAT, it is the NAT that must connect to the EPFL WiFi network. Since we assume that Bart could connect to EPFL, it means that the NAT box succeeded to connect to EPFL. In this case, Bart can connect and Lisa also. The EPFL network sees Bart's NAT and thinks that Bart and Lisa are programs on Bart's NAT.
An example is if Bart uses a PC with virtual box, connects it EPFL, and then uses a guest OS inside the PC.
Admittedly, the answer was not very clear. I updated it.
