Your task is to perform the following: • Add an HTTP firewall rule that allows traffic from the WAN to the web server in the DMZ.
• Add an HTTPS firewall rule that allows traffic from the WAN to the web server in the DMZ. Use the following table for the HTTP and HTTPS rules:

Parameter Setting
From Zone UNSECURE (WAN)
To Zone DMZ
Service HTTP, HTTPS
Action Allow Always
Source Hosts Any
Internal IP Address 172.16.2.100
External IP Address Dedicated WAN

• Add a firewall rule to allow traffic from the LAN to the DMZ.
Parameter Setting
