SD-RED 20 LTE Fallback / primary use

Moving this thread to the Sophos Firewall (XG) Community.

Cheers - Bob

So we have now another 3 days with no update. In the meantime I tested the second SD-RED 20 with the LTE module but same result. There is no fallback to LTE when WAN is disconnected. Does this mean this option is not working at all? Even with the Huawei E3372 stick it is not working.

I am pretty sure the stick is compatible as is is displayed during the SSH console session and while WAN is connected it´s flashing the cyan LED every 2 seconds. If WAN is disconnected the RED LEDs turing some cycles and finally stay in error code "no configuration or firmware update failed" (red-green-green-green flashing) but the LTE stick LED is solid cyan which means the device is connected and registered to the 4G network!

Can you share the configuration for cellular module  ?

Here it is...

Password is "tm". Also tried leaving username/password blank but then it is auto filled by the XGS. Also no luck with APN: internet.v6.telekom. As of the official information from Telekom (Germany) there is no need for username and password.

I am curious about the mobile network setting. It is a drop-down-menu but only GSM is available.

Okay so when connecting on other device it does not require username and password right ?
if you leave it black as per the instruction what's the status then ?
can you confirm with the provider if the APN value is correct ?
Also can you check the logs: tail -f /log/Networkd.log Martin Nowak

The hint with tail helped a lot, it was not the networkd.log but red-R200...xxx.log. After changing the config without the username and password (leaving blank) it worked like a charm but the blink code of the LED is quite unusual when falling back to LTE. It is red-green-green-green flashing all time. Maybe this need to be documented or changed in the firmware.

Hey Martin Nowak thank you for the feedback !
