Assume two hosts on a private network behind a NAT with IP address 192.168.1.4 and 192.168.1.7. They start a communication at the same time with TCP to an external (i.e., on a public network) web server 128.119.245.12 using port 80. The NAT has an internal address 192.168.1.1 and a (single) global address 149.164.33.254 a) Show the address and port fields (for both source and destination) of the two TCP SYN segments on the private network inside the NAT. Assume that the two hosts send TCP SYN fragments towards the web-server with ephemeral port X1 and Y1 (X1 and Y1 may be equal since the addresses differ) b) Propose a NAT binding after the NAT has forwarded the two segments to the c) Show the address and port fields (for both source and destination) of the two TCP d) The server replies with SYN/ACK to both requests. Show the address and port public network.
