What a great god
In the NAT translation, network IP corresponding IP networks outside will write mapping table, if network multiple hosts at the same time access to the same network, outside will assign a different IP? If it is a different IP, if there is a limitation of these mapping table entries? If not, use the same IP networks outside, how the return package is forwarded to each host on the network?

This is not my question
NAT several, we currently use is actually the NAPT, P represents the port number,
NAPT, symmetrical and taper.
Symmetrical distribution of every communication a session, after communication failure.
And cone has a memory function, can be used as a network transmission, namely P2P software.
Taper has three kinds, a kind of is no limit, the second is only initiated by the network first, and the third is also is only initiated by the network first and limit the port
