Remote Access Netgear LB1120

I have a Netgear LB1120 (Uses Cellular network with Dynamic IP) Modem connected to a Linksys Router EA 6350 which the Tablo 4 tuner dvr is connect to using Wifi. I am able to access Tablo from any device while connected to the device but unable to activate remote access. I have setup port forwarding on my router and verified a double NAT issue when I ran tracert on command prompt. Also I previously used AirTV with the same configuration and was able to access remotely. Thanks for any help.
