This solution applies to all Barracuda Web Security Gateway, firmware version and earlier.


The Ultrasurf scanner that was included with firmware version and earlier could potentially blacklist the DNS server's IP addresses, thus preventing further web access through the Web Security Gateway. The issue has been identified and fixed in firmware version and later releases.

Web Security Gateways running firmware will need to be patched by Technical Support. Older firmware will need to be updated to first, before applying the patch.

No further actions required for firmware version and later.
