---**Network Address Translation (NAT) – Educational Example**### QuestionIn the figure, assume the destination of the incoming packet is host 10.0.0.1. What should be the destination port number in the packet (the one marked as ????).### NAT Translation Table| WAN side addr | LAN side addr ||---------------------|-----------------------|| 138.76.29.7, 5001 | 10.0.0.1, 3345 || 138.76.29.7, 6000 | 10.0.0.3, 2200 |### Diagram DescriptionThe diagram illustrates a network setup involving Network Address Translation (NAT). Here's a detailed breakdown of the components:1. **NAT Translation Table**: The table maps Wide Area Network (WAN) addresses to Local Area Network (LAN) addresses and ports.2. **WAN Address**: 138.76.29.73. **LAN Addresses**: - WAN Address 138.76.29.7, port 5001 is mapped to LAN Address 10.0.0.1, port 3345 - WAN Address 138.76.29.7, port 6000 is mapped to LAN Address 10.0.0.3, port 22004. **Incoming Packets**: - Packet from Source (S): 128.119.40.186, port 80 - Destination (D): 138.76.29.7, port ????In the network:- When a packet arrives at WAN address 138.76.29.7 with port 5001, it is directed to LAN address 10.0.0.1 with port 3345.- When a packet arrives at WAN address 138.76.29.7 with port 6000, it is directed to LAN address 10.0.0.3 with port 2200.### Answer Optionsa. 3345 b. 80 c. 5001 d. 6000 ---**Answer Explanation** The correct answer is based on the NAT translation table. If the packet's destination is 10.0.0.1, and according to the table:- WAN Address 138.76.29.7, port

Given that, Destination incoming packet is host 10.0.0.1 Given Network diagram contains one router…
