LTE passthrough routing question

Hi

  • Chateau LTE12, one interface removed from the bridge
  • LTE passthrough configured to that one interface
  • IP address and default route to my router configured on bridge to allow management of the Chateau + Internet access for the Chateau for NTP, firmware upgrades, …

Does the default route interfere in any way with LTE passthrough? Do I need to create multiple routing tables and/or VRFs?

It seems to work just fine but sometimes I have weird issues (internet outages, basically, although LTE signal is perfect and provider says there are no problems, I’m not living in a crowded area either) and it SEEMS to me, that when I remove the default route on the Chateau, the issues are gone.

Thanks
