improving a rule base
You have accepted a position as network administrator for a law firm.
Unfortunately, the previous administrator did not leave much documentation of the network infrastructure and its configuration. you have spent many hours documenting the transmission media, data storage, and device configuration.
you have examined the firewall in an attempt to understand the existing rules and their purpose, and to see whether rewriting the rule base could speed up the firewall’s performance and improve security. Table shows below the notes you have made about the firewall rule base. The firewall works correctly, but some simple changes to the rule base could improve its performance dramatically. The network has IP address from 18.104.22.168 to 22.214.171.124. the firewall is at 126.96.36.199, the web server is at 188.8.131.52, the DNS server is at 184.108.40.206, the SMTP server is at 220.127.116.11 and the POP3 server is at 18.104.22.168
