This module introduced you to the features and functions of NAT. It began by defining NAT's key features.
It then highlighted the design decisions necessary for implementing a functional NAT solution.
Finally, it detailed the processes required for the integration of NAT into an existing network.
At this point, you should be able to:
List the key features of the NAT protocol
List the protocols that the NAT protocol does not support
Describe how to design a functional NAT solution
Identify the processes required to integrate NAT with other services in Windows 10
Describe how to select appropriate server options for a NAT solution
Here is a list of terms used in this module that may be new to you:
- NAT: Network address translation (NAT) is a methodology of remapping one IP address space into another by modifying network address information in
(IP) Internet Protocol datagram packet headers while they are in transit across a traffic routing device.
The technique was originally used for ease of rerouting traffic in IP networks without renumbering every host.
It has become a popular and essential tool in conserving global address space allocations in face of IPv4 address exhaustion by sharing one Internet-routable IP address of a NAT gateway for an entire private network.
- LDAP: (Lightweight Directory Access Protocol) is a software protocol for enabling anyone to locate organizations, individuals, and other resources such as files and devices in a network, whether on the public Internet or on a corporate intranet.
- IPSec: Internet Protocol Security (IPsec) is a protocol suite for secure Internet Protocol (IP) communications by authenticating and encrypting each IP packet of a communication session.
- ISDN:Integrated Services for Digital Network (ISDN) is a set of communication standards for simultaneous digital transmission of voice, video, data, and other network services over the traditional circuits of the public switched telephone network.
- APIPA: Definition of: APIPA. APIPA. (Automatic Private IP Addressing) The Windows function that provides DHCP autoconfiguration addressing. APIPA assigns a class B IP address from 169.254.0.0 to 169.254.255.255 to the client when a DHCP server is either permanently or temporarily unavailable.
- DHCP Allocator
In the next module, you will learn what is involved in securing and enhancing NAT design for availability.
