When setting up a new hardware Sophos Firewall, what is the default IP address and port to access the device?

The default IP address and port to access a new hardware Sophos Firewall is 172.16.16.16:4444. This configuration is specifically designated for initial management connections to the device. When setting up a new firewall, this particular IP address and port allow administrators to access the management interface for the first time.

Using this specific address is crucial as it is standardized for Sophos devices, guiding users to ensure they are connecting to the correct default setting without confusion. Accessing the firewall through this IP and port makes it straightforward for users to begin configuration processes, such as setting up networking settings, security rules, and other essential management tasks right from deployment.

Other options listed in the question pertain to different IP configurations, which are not the default settings for a Sophos Firewall, thus would not be functional as an initial access point.
