Why is it that I have to use the Xfi app to set port forwarding??? It was sooooo much easier when I could go into the modem and set the IP addresses and ports directly. The device I am trying to set up port forwarding for rarely shows as being "online" even though the device is connected to my network and passing traffic. I am an experienced IT professional so I have no problem setting up the modem on my own. To me the app is worthless. It may be alright for someone with limited experience but not for people that know what they are doing.
