LM1200 repeatedly dropping link

I recently purchased an LM1200-100NAS to serve as an LTE failover connection for my homelab and noticed a strange issue while setting up my pfSense-based router to use the LM1200 as a secondary WAN c...

My keep alive was already set at the minimal interval of 1 minute. I checked this all again and added the address 8.8.8.8, and google.com to ping. The process is still the same, as soon as i plug my sonicwall in the port pulls a dhcp address and then the LM1200 wan port shuts down. Rendering the connection useless. So I then uplug the firewall and plug in my laptop. The port comes back up and I can pull another DHCP address from Verizon and surf the net without issue. Why does this seem to be happening with wan ports on routing devices?

There are a lot of post here in this forum of people having similiar issues across multiple devices.

Please make sure you connect your sonicwall to the LAN port of the LM1200. The WAN port on LM1200 is for connecting your home broadband.

John,

It is connected to the LAN port on the LM1200 to the WAN port on the SonicWALL, sorry for the confusion. The WAN port on the LM1200 will not be used as this is a mobile setup. So what do i do next? RMA the device or throw it in the trash and find another vendor? Cut my losses now?

    Based on the logs captured so far, we could see that the data connection was torn down by the network. We are still working with Verizon to find the root cause of the issue. Most of Verizon customers don't have the issue.
