WSUS not syncing correctly in SonicWall environment

I have a client whose Windows Server Update Services (WSUS) was not syncing correctly and therefor computers were not getting updated. The event viewer logs on the server had the following entry:

Event Type: Error
Event Source: Windows Server Update Services
Event Category: Synchronization
Event ID: 364
Description:Content file download failed.
Reason: The server does not support the necessary HTTP protocol. Background Intelligent Transfer Service (BITS) requires that the server support the Range protocol header. Source File: /msdownload/update/v3-19990518/cabpool/ Destination File: F:\WSUS\WsusContent\3B\

Microsoft KB 922330 resolution method 2 was to "Enable HTTP Byte-Range request with Gateway AV" on the SonicWall firewall.

To get to the Sonicwall setting log onto your firewall. After you have logged on, change the URL from /main.html to /diag.html. Click Internal Settings button. Check "Enable HTTP Byte-Range requests with Gateway AV". Click Apply button. Click Close button. Restart is not required.

Test WSUS by manually syncing. Sync should begin.

Thanks to this site for the info
