Thank you John.
I switched to Router mode and I was able get the traffic through. That caused me another problem since the port numbers using public IP was not translated to local IP.

Thanks for all the help, now I need to find external antennas to improve the LTE reception.

I have run the firmware update, and both ports appear to be live. I want the device's cellular as a failover only. I have connected from arris modem to nighthawk rax80 router. What is the best setting for successful failover? Bridge, Ping frequency, and router setting recommendations? Etc.

Depending on your purpose, if you plans to use LM1200's failover as backup for all your network, it is better to set up LM1200 the following way.
Arris Modem -> LM1200 WAN Port - LM1200 LAN Port -> RAX80.
When Arris fails, LM1200 can switch to 4G network to make sure RAX80 can have data connections.
Thanks

I can't seem to get the lm1200 to work as a pass-through with the wireline. Im sure it's something simple, but I don't know what it is!
