AT&T Gateway address updates

Well our friends at AT&T are up to changes in the network again. Happily they were kind enough to send out a message with a heads up about new network addresses that are coming from devices on their network.

If your applications use IP addresses to either identify or limit who or how you grant access, take a moment to review this update from AT&T to modify your firewalls/apps/etc.. as needed.
