Expert Solution & Answer
Chapter 6, Problem 13RQ
Explanation of Solution
PAT:
PAT stands for Port Address Translation, an extension of Network Address Translation, which allows multiple devices on LAN (Local Area Network) to be mapped to be a single public Internet Protocol (IP) address. The aim of PAT is to preserve IP address.
Working method of PAT:
It converts external IP address into particular ranges of Internal IP address based on one-to-many basis...
