Hi,
Is there any guide to set up an LTE fallback gateway using a cheap Huawei USB modem key (12d1:1f01 Huawei Technologies Co., Ltd. E353/E3131)?
I've successfully switched it to NCM mode (12d1:155e) or ECM mode (12d1:14db), but I do not know what to do to move forward:
* in NCM mode, ue0 interface is successfully detected:
ue0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500
ether 00:1e:10:1f:00:00
nd6 options=23<PERFORMNUD,ACCEPT_RTADV,AUTO_LINKLOCAL>
however I do not know how to configure such an interface with opnsense;
* in ECM mode, the network interface does not show up in opnsense UI (nor via CLI/SSH).
In this later mode, Linux automatically assigned a local IP to the interface from the integrated DHCP server on the USB modem key (192.168.8.0/24), but I did not find how to do something akin to Linux with opnsense/freebsd.
Thanks.
