In Remote upgrades, your Cisco IronPort appliances download the AsyncOS
upgrades from a server within your network. You only download the upgrade
image from Cisco IronPort one time, and then serve it to your Cisco IronPort
appliances.

IronPort appliance downloads the upgrade separately.
Cisco IronPort Systems uses a distributed upgrade server architecture to make
sure customers can quickly download AsyncOS upgrades wherever in the world
they are located. Because of this distributed server architecture, the Cisco
IronPort update servers use dynamic IP addresses. If you have strict firewall
policies, you may need to configure a static location for AsyncOS upgrades. If
you determine that your firewall settings require a static IP for upgrades, contact
Cisco IronPort Customer support to obtain the required URL addresses.
