3 Proxies and caching Network modes Network modes Web cache settings The web cache settings are part of the proxy settings. You can review and modify both on the same tab of the user interface. The web cache is by default enabled after the initial setup, but its use is controlled by web security rules. A web cache rule set must be implemented with rules for writing to the cache and reading from it. You can review the implemented rule sets on the Rule Sets tab of the Policy top-level menu. If no web cache rule set is implemented, you can import one from the rule set library or create a web cache rule set with rules of your own. For more information, see Web caching. The appliance can operate in different network modes to intercept and filter web traffic. This section explains these modes and tells you how to configure them. • Explicit proxy mode — In this mode, the clients of the appliance are generally aware of its existence. You can use one of the following options to implement this mode: • Proxy — This is the explicit proxy mode proper. It is preconfigured on the appliance. Optionally, you can configure this mode to let it use several transparent features. For example, you can configure the use of WCCP services. Requests sent from clients can then be directed to the appliance by these services and back from web servers to the appliance. The clients are not aware of these redirections. You can also configure a method for using client IP addresses that is known as IP address spoofing (IP spoofing). Client requests that are intercepted on the appliance are then passed on to web servers with their original source addresses, not with that of the appliance. • Proxy HA — The appliance operates as an explicit proxy that is configured as a part of a high-availability configuration. • Transparent bridge mode — Clients are unware of the appliance, which serves as an (invisible) bridge between a firewall and the rest of your network. • Transparent router mode — Clients are unware of the appliance, which serves as a router in your network, directing web traffic according to a routing table. 38 McAfee Web Gateway 7.1.5 Product Guide
Explicit proxy mode Proxies and caching Network modes 3 This section explains the explicit proxy mode and how to configure it on the appliance and its clients. In this mode, the clients that have their web traffic filtered by the appliance “know” they are connected to it. They must explicitly be configured to direct their web traffic to the appliance. If this is ensured, it is less important where the appliance is deployed within your network. Typically, it is placed behind a firewall and connected to its clients and the firewall by a router. The following diagram shows a configuration in explicit proxy mode: Figure 3-1 Explicit proxy mode Configure the explicit proxy mode This section tells you how to configure the explicit proxy mode for the appliance. 1 Go to Configuration | Appliances. 2 On the appliances tree, go to the appliance you want to configure settings for and select Proxies (HTTP(S), FTP, ICAP, and IM). 3 Under Network Setup, select one of the options for the explicit proxy mode: • Proxy — For the explicit proxy mode proper Note: This option is preconfigured after the initial setup. When it is selected, specific settings for configuring a proxy mode with transparent features appear below the Network Setup settings. • Proxy HA — For an explicit proxy mode with high-availability functions Note: After selecting this option, specific Proxy HA settings appear below the Network Setup settings. 4 Configure specific and common settings for the selected option as needed. 5 Click Save Changes. For more information, see Transparent Proxy and Common proxy settings. McAfee Web Gateway 7.1.5 Product Guide 39
