What NAT is and why I need it

NAT (Network Address Translation) is a translation of private IP addresses to external. Due to this process the virtual machine gets access to the Internet.

In private networks “gray” IP addresses are being used which cannot be used in the Internet.

In order to have Internet access a white IP address is required which will masquerade one or several private IP addresses.

NAT mechanism implements substitute (or masquerade) of gray addresses into white and vice versa.
