Adding an override server
If you cannot connect to the FDN or if your organization provides antivirus and attack
updates using their own FortiResponse server, you can use the following procedure to
add the IP address of an override FortiResponse server.
1 Go to System > Update.
2 Select Use override server address and add the IP address of a FortiResponse
server.
3 Select Apply.
The FortiGate unit tests the connection to the override server.
If the FortiResponse Distribution Network setting changes to available, the FortiGate
unit has successfully connected to the override server.
If the FortiResponse Distribution Network stays set to not available, the FortiGate unit
cannot connect to the override server. Check the FortiGate configuration and the
network configuration to make sure you can connect to the override FortiResponse
server from the FortiGate unit.
Manually updating antivirus and attack definitions
You can use the following procedure to update the antivirus and attack definitions at
any time. To run this procedure the FortiGate unit must be able to connect to the FDN
or to an override FortiResponse server.
1 Go to System > Update.
2 Select Update Now to update the antivirus and attack definitions.
If the connection to the FDN or override server is successful, the web-based manager
displays a message similar to the following:
Your update request has been sent. Your database will be updated
in a few minutes. Please check your update page for the status
of the update.
After a few minutes, if an update is available, the System Update page lists new
version information for antivirus definitions, the antivirus engine, or for attack
definitions. The System Status page will also displays new dates and version numbers
for antivirus and attack definitions. Messages are recorded to the event log indicating
whether the update was successful or not.
Configuring push updates
The FDN can push updates to FortiGate units to provide the fastest possible response
to critical situations. You must register the FortiGate unit before it can receive push
updates. See
“Registering the FortiGate unit” on page 102 .
If the FDN must connect to the FortiGate unit through a NAT device, see “Push
updates through a NAT device” on page 96 .
Push updates are not supported if the FortiGate unit must use a proxy server to
connect to the FDN. See
“Scheduled updates through a proxy server” on page 100 for
more information.
