Lesson 7

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:

1. List the key features of the NAT protocol
2. List the protocols that the NAT protocol does not support
3. Describe how to design a functional NAT solution
4. Identify the processes required to integrate NAT with other services in Windows 10
5. 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:

1. 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.
2. 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.
3. RPC: In distributed computing, a remote procedure call (RPC) is when a computer program causes a procedure to execute in a different address space on a shared network, which is coded as if it were a normal (local) procedure call, without the programmer explicitly coding the details for the remote interaction.
4. 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.
5. 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.
6. 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.
7. DHCP:The Dynamic Host Configuration Protocol (DHCP) is a network management protocol used on UDP/IP networks whereby a DHCP server dynamically assigns an IP address and other network configuration parameters to each device on a network so they can communicate with other IP networks
8. DHCP Allocator: The allocator defends each address on the network before assigning the address, and the allocator makes the address assignments for configurable periods of time to avoid collisions that arise when devices are not operating. The default period for address assignment is ten minutes.

In the next module, you will learn what is involved in securing and enhancing NAT design for availability.
