RUT241 in Bridge or Passthrough with 4G unstable

[Fleron]

Hi
When the RUT is running in NAT with a 4G simcard , the internet connection is super stable but when changing the WAN to either run Bridge or Passthrough, I get a lot of connection drops. Changing it back to NAT and connection works fine again. I’m doing the test directly to the 241 with a device in order to exclude any issues with my Ubiquitu XG.
I have tried two different sim card vendors and one with static ip, but still no change in this behavior.
I have followed the guide RUT241 WAN - Teltonika Networks Wiki and just changed the WAN to Bridge.
The issue is the internet connection is really unstable and I’m unable to ping / tracert to an external most of the times when the RUT is running either bridge or passthrough. I have also tried to remove any IPv6 but that did not help.
Any ideas on why I’m seeing this.
Dennis

Hi
I got this to work after some fiddling around by resetting back to factory default, upgraded to latest firmware and then start over with the WWAN and then is started to work.
So for now, please close the case as I have it working.
Thanks
