A client computer uses the IP address 10.254.254.189 . It has made a connection to a web server by opening the outbound port 1589 . The server uses the IP address 65.19.28.154 . You want to filter out any HTTP packets coming from the server. Which IP address and port should you specify to be filtered on the firewall?
A. 10.254.254.189:1589
B. 10.254.254.189:80
C. 65.19.28.154: 1589
D. 65.19.28.154:80
D. You should filter the packets coming from the server's IP and its inbound port: 65.19.28.154:80 . It would be difficult to filter Port 1589 because this port is assigned dynamically to the outbound connection of the client computer; it will change every time a new session starts. The client computer should not use Port 80 because it is not the computer acting as a web server. The web server will most likely not use Port 1589 . The connection from the client computer on outbound Port 1589 is made to the web server on inbound Port 80.
