When configuring the Web proxy feature, where must the proxy server be placed?

When configuring the Web proxy feature, placing the proxy server in the DMZ or WAN zones is essential for several reasons. The DMZ (Demilitarized Zone) serves as a buffer between the internal network and the external Internet, allowing secure access to services while protecting sensitive internal resources. By positioning the proxy server in one of these zones, it can effectively manage and filter outbound web traffic from the internal network to the Internet and vice versa.

Furthermore, placing the proxy in the DMZ or WAN zones allows it to handle requests from external users who may require access to internal resources (if allowed) while still maintaining a secure separation from the internal LAN. This setup enhances security by minimizing the risk of external threats reaching the internal network directly.

In contrast, placing the proxy server in the LAN zone would expose it to potential vulnerabilities from within the internal network, and positioning it in other zones, such as the VPN zone, wouldn't effectively handle external web traffic or provide the necessary filtering and caching functionalities typically utilized by a web proxy. Therefore, the choice of situating the proxy server in the DMZ or WAN zones is crucial for effective web traffic management and overall network security.
