Anyone know of a reasonably-priced 4G (or later) USB stick that'll Just Work™ in a oldish Mikrotik box? It's sitting on top of a rack in the datacentre to give me emergency access when needed, currently using a 3G USB stick I had lying around. Ideally I'd like to find a stick that'll be willing to pass through a public IP address to the host, but I haven't been able to find anything that seems to do that. The current 3G stick insists on NATing, so if I have to accept NAT, it's no worse than at present - I just maintain an outbound tunnel to a third-party VM I already have elsewhere and log in through that. It's one more step I could get rid of though. At the moment one solution I'm seeing is to replace the whole Mikrotik box with the cheapest one that has a cellular data modem built in for circa £100, but it'd be nice to generate less e-waste and (hopefully) spend less by replacing only the USB stick.
