Which deployment mode is NOT available for WatchGuard Firebox?

Proxy Mode is the deployment mode that is not available for WatchGuard Firebox. The Firebox uses several other modes to accommodate different network scenarios, but proxy-based deployment is not included among them. In environments where packet-level filtering is needed and where traffic is inspected without being routed through a proxy, the device may operate in modes like Gateway (Router) Mode, Mixed Mode, or Interface (Transparent) Mode.

In Gateway (Router) Mode, the Firebox acts as a default gateway for the devices on your network, managing traffic efficiently. Mixed Mode combines the functions of both Gateway and Transparent modes, allowing the firewall to operate as a router while also performing layer 2 functions. Interface (Transparent) Mode enables the Firebox to integrate more seamlessly into existing network infrastructure by allowing it to operate without altering the network's architecture. Each of these modes serves specific purposes and provides flexibility in deployment, while Proxy Mode, which typically involves intermediate handling of traffic via a proxy server, is not part of the Firebox's deployment options.
