Hello, i recently bought a Huawei E3372 Hi-Link LTE Dongle and got a data simcard from work to provide 4G failover at home.
So far im able to get a Ethernet interface out of the dongle (plug and play no magic) i get my VyOS router to have 192.168.8.2/24 as IP and the dongle has 192.168.8.1/24 as IP, and when i ping the dongle IP it seems to vary a lot in response times ( as if im pinging the 4G cell tower) so that is a good start. Also i have tested the modem on my laptop without configuring it beforehand and it auto connects to the Internet so it is autoconfigured.
My own minor problem is that since the modem is a router in it self and it means it is a double nat configuration which i cant seem to find a reliable source for. This prevents me from pinging 184.108.40.206 and reach the overall outside Internet via the 4G connection.

Can anyone help ?
Currently i have looked at forum posts here and on OpenWRT to get a general idea.
