BORDER-BLOCK-SMB filter will be updated on January 21 from 9:00am and 11:00am

The existing BORDER-BLOCK-SMB network filter will be updated to include udp ports 1026, 1027, and 1028. These ports are used by the Windows Messenger service to distribute spam messages to unprotected computers. No action will be required by current users of this filter to take advantage of this addition. Network administrators wanting to take advantage of this filter may activate it in the Transmogrifier. No Service Outage expected.
