Cisco Vs Huawei LAB L – (Configuring NAT Overloading & PAT)

Port address translation (PAT), which is also called network address port translation (NAPT), maps a public address to multiple private addresses. Therefore, public addresses are saved. PAT translates source IP addresses of packets from hosts that reside on the private network to a public address. The translated port numbers of these packets are different, and the private addresses can share a public address.
