Kevin is at a computer behind a NAT gateway. The computer’s IP address is 192.168.1.100. He opens a TCP connection to a Web server at einsec.com. Use the standard port number and socket address definition described in Section 11.3.

a. Using the IP address for einsec.com looked up in Section 12.3.3 and the source port number of 44366, give the full socket address for the connection to the Web server.

b. How does a NAT gateway choose a port number for an outgoing packet? Use that technique to choose a port number for this packet.

 c. Assume that the NAT gateway has a global IP address of 11.22.33.44. Using the NAT port number chosen in (b), give the full socket address as seen by the server.
