HTTP response Router Y 7. [11pts) DHCP&NAT. Consider the network shown in NAT translation table right. Hosts A, B, and C are behind the NAT box (which WAN side addr LAN side addr is also a DHCP server and has a single global IP address), 138.76.29.7.1001 10.0.0.10, 3000 and a Web server is outside NAT and has a global IP Router X NAT & DHCP box address and port number (128.119.40.186, 80). Answer the Internet following problems. 10.0.0.1 Web server IP: 128.119.40.186,80 DHCP discover (a) [3pts] Host A has just sent an HTTP request to the Web /offer/request/ack server, and the NAT table has been updated as shown in the figure. What will be the source/destination IP/port numbers of the HTTP response when transmitted by Web server (O), and when receive by host A(?). HTTP response HTTP response 1 src. port dest. IP HTTP response ? src. port dest. IP src. IP dest. Port src. IP dest. Port (b) [3pts] Host C has newly arrived in the private network, DHCP source IP address and tries to aqcuire a new IP address via DHCP. Fill in the discover blanks in right no need port) destination IP address DHCP 10.0.0.1 source IP address offer destination IP address c) [2pts] Choose all the information that a DHCP client obtain from the DHCP server after a successful communication between the two. (Select all answers) A. IP Address B. IP address of the first hop router C. IP address of local DNS server D. network mask (d) [3pts] Let's discuss the impact of NAT on peer-to-peer applications.
