Hi. I just recently signed up for the LTE network. I have an MBR1000 Cradlepoint router connected thru a UML290 modem. My new addess is no longer publically routable (as 10.x.x.x). I need to access my home/office security camera system. I used to use DDNS with my old USB760, but this option no longer works on the new LTE net. Any suggestions from anyone?
