In this lab, your task is to perform the following:
Access the pfSense management console:Username: adminPassword: P@ssw0rd (zero)
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:ParameterSettingSourceWANSource and destination
