The selected Mikrotik Routerboards have the USB port. This port is intended to be used either as an additional storage or to connect different external devices, like the USB 3G modem. Now, if you have the USB modem and only Mikrotik VM, what can you do?
Of course, we should use the magic. We can redirect the USB device from the host to the VirtualBox guest. I already described this mechanism in this post. However, we have here a few more steps.
Ready? Then let’s begin.
