Just like hosts within the first category, such hosts may use IP addresses that are unambiguous within an enterprise, but may be ambiguous between enterprises. Category 3: hosts that need network layer access outside the enterprise (provided ...
The NAT-enabledIPv4router allows home network devices to use one public IPaddressthat it has got from a provider on the WAN interface for the Internet connection. This external public IPaddresscan be used to access home network devices from the Internet as well, but for this purpose, it is necessary to set up Port forwarding on your router.
