Q15: Consider the scenario below in which three hosts, with private IP addresses 10.0.1.13, 10.0.1.15, 10.0.1.21 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 the IP address 10.0.1.27, while the router's address on the Internet side has the IP address 135.122.200.210. Suppose that the host with IP address 10.0.1.21 sends an IP datagram destined to host 128.119.164.182. According to the following topology, show the source and destination IP address for each step S: (2) D: S: D: NAT translation table WAN side addr LAN side addr 3 135,122,200,210 135.122.200.210 10.0.1.21 10.0.1.27 S: D: 1 S: D: 4 10.0.1.13 10.0.1.15 10,0,1,21
