Note
Only use a local update server for upgrade images, not update images. When you
specify a local update server, the local server does not automatically receive
updated security service updates from IronPort, so the appliances in your network
eventually become out of date. Use a local update server for upgrading AsyncOS,
and then change the update and upgrade settings back to use the IronPort update
servers so the security services update automatically again.
