I understand that ipfire can do failover to a 4G WAN.
The documentation here says to use a compatible modem from the list it provides, however, I, for the life of me, cannot see a list of compatible modems.
Failing this, is it possible for me to use on of those LTE to ETH devices that just hands out DHCP lease through Ethernet, and I can set that as a failover WAN 2?
Can’t seem to find any information, I see a page about dial-up settings but I assume that is for talking to a USB modem directly right? Do we have to use a USB modem directly for WAN failover or can we use something like one of these 4G LTE - Protectli (Not for me in Australia but similar device) for the failover WAN?
