xfi Advanced Security prevents email downloads

xfi advance security also has issues with their own comcast emails and Hotmail. When starting Outlook 365, comcast email takes a long time to come in, hotmail can't connect (error messages, trying to connect) for about 5 min, then it starts to sync with exchange server. Turning off advanced security fixes it, but that's not what should happen. Why have xfi Advanced security if you have to turn it off.
