June 27, 2013
THIS FIELD NOTICE IS PROVIDED ON AN "AS IS" BASIS AND DOES NOT IMPLY ANY KIND OF GUARANTEE OR WARRANTY, INCLUDING THE WARRANTY OF MERCHANTABILITY.

Initial Public Release
Cisco will soon release new improvements to its Security Intelligence Operations infrastructure that enable greater scalability and efficacy to all Cisco security products. As part of this effort, there is a scheduled change to the IPv4 addresses for one host used to retrieve updates to all services, except McAfee Anti-Virus definitions for the Cisco Email Security Appliances (ESAs). Cisco Email Encryption Appliances also use this host to download license keys.
By default, Cisco security technologies use Domain Name System (DNS) to locate the appropriate update servers. However, some environments might have configured static IP addresses in their access control. If you have configured IP-based access control in order to permit outbound connections for updates from Cisco, you need to modify your rules to support the new IP address.
Customers that have configured IP-based access control to permit outbound connections for updates from Cisco need to modify the rules to support the new IP address prior to June 28, 2013.
If the new IP addresses are not added to the access control, Cisco Email Security Appliance will not receive updates and the Encryption Appliance will not download new license keys.
If these IP addresses have been added to your access control policy:
downloads-static.ironport.com has address IPv4 address 22.214.171.124
Note: This site is used for all services (except McAfee Anti-Virus definitions on TCP Port 80) on Email Security Appliance and to download license keys on Encryption Appliance.
Add these IP address to your access control policy by June 28, 2013:
downloads-static.ironport.com will have IPv4 address 126.96.36.199
If you do not modify the necessary access controls, your Cisco Email Security Appliance will not receive updates and your Encryption Appliance will not download new license keys.
Should you have any questions, contact your local Cisco Support Team.
