Suppose that a NAT is between the Internet and a company's network. Now suppose that the NAT crashes, but quickly restarts, in a very short amount of time. How would a short-lived reboot impact the users and machines in the company's network?

There would be no internet connection during the duration of the reboot.

Explanation:

NAT or network address translation protocol is used to translate or substitute private IPv4 network addresses with public IPv4 addresses to gain access to internet resources. Private IPv4 addresses are not routable on the internet and due to the exhaustion of the IPv4 addresses, the NAT maps the private network with a limited amount of public addresses (public IPv4 network addresses are routable on the internet).

i don't think so. although it would be nice. i am pretty sure that was an option an update or two ago. i guess they want you to stay 14 forever. haha.
