How to set up your FortiWeb : Connecting to FortiGuard services : Accessing FortiGuard via a web proxy
 
Accessing FortiGuard via a web proxy
Using the CLI, you can configure the FortiWeb appliance to connect through an explicit (non-transparent) web proxy server to the FortiGuard Distribution Network (FDN) for signature updates.
For example, you might enter the following commands:
config system autoupdate tunneling
set status enable
set address 192.168.1.10
set port 8080
set username FortiWeb
set password myPassword1
end
For details, see the FortiWeb CLI Reference.
The FortiWeb appliance connects to the proxy using the HTTP CONNECT method, as described in RFC 2616.
