Operational Modes > Invisible Mode:

Administrator Console Settings
If the Web Filter is set up in the invisible mode, the unit will filter all connections on the Ethernet between client PCs and the Internet, without stopping each IP packet on the same Ethernet segment. The unit will only intercept a session if an inappropriate request was submitted by a client. In this scenario, the Web Filter returns a message to the client and server to deny the request, and a block page displays to deny the client access to the site or service.

When users (Client PCs) make Internet requests, the traffic flows through the network path without interruption. The Web Filter captures the request as the user’s request leaves the network. The Web Filter then determines the action to either block or pass the request. If the Web Filter determines to block the user’s request, a block message is sent to the user plus a terminate message is sent to the Internet server.

Hardware Settings
A Web Filter unit set up to work in the invisible mode can be physically configured to work in the router mode. In this setup, the Web Filter port is configured with the port monitoring function enabled, so that the Web Filter’s port mirrors the port connected to the router.

In the invisible mode, the Web Filter performs as a standalone server that can be connected to any network environment.
