Hi Aaron, We use the Sierra Wireless USB 320 modems, picked up on ebay for about $40 or so, they just show as an LTE interface, then you setup DHCP on that interface so you could bridge it through to another device if you needed as well I suppose.

Does anyone have a USB LTE modem working in Mikrotik without the NAT/DMZ/router mode? Whether it be a ppp interface or LTE. We are aware of the newer wAP LTE Kit and have a few of them out working perfectly (Thanks DuxTel & Mike!) in passthrough mode for failover but we want to see what options are there for USBs. We have an Optus layer 2 setup so we chuck our IPs on it. https://wiki.mikrotik.com/wiki/Manual:Peripherals is a good list; but a modem that’s listed as ‘working’ may still have the double NAT situation so we are hesitant to go out and buy 10 different USB modems to see which works.
