This article lists the steps to download the signatures of GAV / IPS / Anti-Spyware via Proxy.
Important: The SonicWall must not be synchronized with my SonicWall using the "Update your Registration" button. If the SonicWall is already registered and licensed, pelase follow these steps:
SonicWall Security Services Signatures are downloaded from License Managers (LM) using HTTPS. However, signature downloads fail when 1) SonicWall Web Proxy forwarding is configured to forward all traffic to a proxy server on the WAN 2) all traffic from the SonicWall is forced through a gateway web proxy device.
Until SonicOS 5.6, in such closed environments the only solution would have been to download the signature file from mysonicwall.com and upload it into the SonicWall UTM appliance manually. Starting with SonicOS 5.8.x, it is possible to download signatures through a proxy server.
After all the licenses are displayed into the SonicWall, navigate to the Security Services | Summary page:
Enable the check box under Download Signatures through a Proxy Server under Signature Downloads Through a Proxy Server
Enter the name or IP address of the proxy server under Proxy Server Name or IP Address
Enter proxy server port number under Proxy Server Port
If the proxy requires authentication to allow access, check This Proxy Server requires Authentication and provide the username and password of an account that is authorized to access the Internet through this proxy.
In Network Security Portal Username and Network Security Portal Password, type MySonicWall Username and Password to which the appliance is registered. N.B. Use only username and password to which the appliance is registered.
Click Accept at the top of the web-page.
Please, re-type Proxy Server password and MySonicWall Password and then click the Synchronize button. It takes a while but now you should see the following fields disappear.
Now all the Security Services should begin the signatures download and the licenses should be displayed under System | Licenses.
