Deployment of the appliance Before you set up the McAfee Web Gateway appliance, consider how you want to use it. You can run it on different platforms and configure different modes of network integration. You can also set up and administer multiple appliances as nodes in a Central Management configuration. Platform You can run the appliance on different platforms. Hardware-based appliance — On a physical hardware platform Virtual appliance — On a virtual machine Network integration In your network, the appliance can intercept, filter, and transmit web traffic in different modes. Explicit proxy mode — The clients that the appliance communicates with are aware of it. You must configure them “explicitly” to direct their traffic to the appliance. Transparent modes — The clients are not aware of the appliance. Transparent bridge — The appliance acts as an “invisible” bridge between its clients and the web. You need not configure the clients for this. Transparent router — The appliance routes traffic according to a routing table, which you need to fill out. Administration and updates You can administer the appliance and have updates distributed in different ways. Standalone — Administer the appliance separately and let it not receive updates from other appliances. Central Management — Set up the appliance as a node in a complex configuration and administer other nodes on its user interface, including the distribution of updates. You can then administer the appliance on other nodes and let it receive updates from them.
