How does NAT (network address translation) help protect outsider access to computers in a home network?
What will be an ideal response?
The bad guy sees only the router because the IP addresses of the internal networking

router is provided. A home network typically uses private address space that
is not routable on the Internet. (Private IP addresses are blocked by the ISP.)
