Chapter 23 WAN Optimization, Web Cache, Explicit Proxy, and WCCP : The FortiGate explicit web proxy : Example: users on an internal network browsing the Internet through the explicit web proxy with web caching, RADIUS authentication, web filtering and virus scanning
  
Example: users on an internal network browsing the Internet through the explicit web proxy with web caching, RADIUS authentication, web filtering and virus scanning
This example describes how to configure the explicit web proxy for the example network shown in Figure 343. In this example, users on the internal network connect to the explicit web proxy through the Internal interface of the FortiGate unit. The explicit web proxy is configured to use port 8888 so users must configure their web browser proxy settings to use port 8888 and IP address 10.31.101.100.

Explicit web proxy users must authenticate with a RADIUS server before getting access to the proxy. The explicit proxy policy that accepts explicit web proxy traffic applies per session authentication and includes a RADIUS server user group. The authentication rule also applies web filtering and virus scanning.
