The FortiGate unit sends the override push IP address and Port to the FDN. The FDN

Scheduled updates through a proxy server
If your FortiGate unit must connect to the Internet through a proxy server, you can use
the set system autoupdate tunneling command to allow the FortiGate unit to
connect (or tunnel) to the FDN using the proxy server. Using the command you can
specify the IP address and port of the proxy server. As well, if the proxy server
requires authentication, you can add the user name and password required for the
proxy server to the autoupdate configuration. The full syntax for enabling updates
through a proxy server is:
set system autouopdate tunneling enable [address
<proxy-address_ip> [port <proxy-port> [username <username_str>
[password <password_str>]]]]
For example, if the IP address of the proxy server is 64.23.6.89 and its port is 8080,
enter the following command:
set system autouopdate tunneling enable address 64.23.6.89
port 8080
For more information about the set system autoupdate command, see Volume 6,
FortiGate CLI Reference Guide.
The FortiGate unit connects to the proxy server using the HTTP CONNECT method,
as described in RFC 2616. The FortiGate unit sends an HTTP CONNECT request to
the proxy server (optionally with authentication information) specifying the IP address
and port required to connect to the FDN. The proxy server establishes the connection
to the FDN and passes information between the FortiGate unit and the FDN.
The CONNECT method is used mostly for tunneling SSL traffic. Some proxy servers
won't allow the CONNECT to connect to just any port; they restrict the allowed ports to
the well known ports for HTTPS and perhaps some other similar services. Because
FortiGate autoupdates use HTTPS on port 8890 to connect to the FDN, your proxy
server may have to be configured to allow connections on this port.
