What is the primary function of a Public Server in a firewall setup?

The primary function of a Public Server in a firewall setup is to facilitate external access to internal resources, acting as a bridge between the internal network and external users. This typically involves hosting services such as web servers, mail servers, or file servers that need to be accessible from the internet.

The Public Server is configured with specific rules in the firewall that allow inbound connections while protecting the internal network. This setup is essential for businesses that require external users, such as customers or partners, to access information or services securely without exposing the entire internal network to potential threats. By deploying the Public Server in this manner, it enables controlled access to the internal servers, ensuring that sensitive data remains protected while still being available to authorized external parties.

This role is crucial in maintaining both the functionality of the services offered and the security of the network.
