The figure below shows a network with a NAT router. In step 1, host 10.0.0.1 sends a datagram from its port 3345 to host 128.F19.40.186's port 80. The router will use the NAT translation table to determine the source and destination IP addresses and port numbers of the datagram it will forward. In step 2. the destination IP address and port number of the outgoing datagram are provided for you. Determine the source IP address and port number of this datagram.
