Руководство Пользователя для Cisco Cisco Email Security Appliance C170

The Cisco IronPort update servers use dynamic IP addresses. If you have strict firewall policies, you may 
need to configure a static location for security component updates and AsyncOS upgrades. If you 
determine that your firewall settings require a static IP address for updates and upgrades, follow 
instructions below for editing the update settings and contact Cisco IronPort Customer support to obtain 
the required URL addresses.

To edit the update settings for your Cisco IronPort appliance, click the Edit Update Settings button. You 
can configure the following types of settings: Update Servers (images), Update Servers (list), Automatic 
Updates, Interface, and Proxy Servers. See
