Consider the scenario below in which three hosts, with private IP addresses 10.0.1.13, 10.0.1.15, 10.0.1.18 are in a local network behind a NAT'd router that sits between these three hosts and the larger Internet. IP datagrams being sent from, or destined to, these three hosts must pass through this NAT router. The router’s interface on the LAN side has IP address 10.0.1.27, while the router’s address on the Internet side has IP address 135.122.195.214
Suppose that the host with IP address 10.0.1.18 sends an IP datagram destined to host 128.119.165.185. The source port is 3419, and the destination port is 80.
At step 3, what is the destination IP address for this datagram?
