I use an 4G USB modem as red0 interface. This is a Alcatel IK40 (also named L850V from lsusb). It works fine, just configuring the red0 interface as DHCP and everythings is ok.
Only problem, is at each reboot, the modem assign a new MAC adress so IPfire fails to detect it at startup.when connecting to the modem (192.168.1.1) the modem embled website don’t offer any option to disable this. also no ssh allowed.
Do I have any option to detect red0 with else than MAC adress? ex: USB device id ?
