Your host in this example has IP address 172.16.1.1. Someone tries to send e-mail from a remote host with IP address 192.168.3.4. If successful, this generates an SMTP dialogue between the remote user and the SMTP server on your host consisting of SMTP commands and mail where TCP connection is set up between a user agent and a server program. The server listens on TCP port 25 for incoming connection requests. The user end of the connection is on a TCP port number above 1023 Additionally, assume that a user on your host tries to send e-mail to the SMTP server on the remote system For each of the following Four packets generated in this scenario: 1. fill in the table here as follows based on our ruleset (Table. 1): In the Action cell specify the action that was performed (by writing "Permitted" or Denied").-Please use the exact spelling to avoid loosing point (no quotations) .
