NAT
NAT (Network Address Translation) converts an IP address, for example of a private network, into an IP address on the public network. This gives all computers that communicate with each other in the private network access to the Internet via a single IP address. However, the internal IP addresses on the private network are not accessible for the Internet.
Requirements for configuration
