Topology
In this article will be given a step by step tutorial to use the USB port for the modem, as the picture of the network, this tutorial uses the RouterBoard Indoor RB751U-2HnD and 3G sierra 881U modem, which forms the topology like the one in the image below:Here are some steps we have to do in the configuration:
IP Address
The first step we add our router is the IP address on the interface that will be used for the local network.
Wireless Access Point
The next wlan1 enable interface as an access point for the distribution of wireless connection to a local network.
DNS
For the DNS settings we need to enable the parameter 'allow remote request' so that our client can request the DNS to our router.
USB Devices
If the IP interface (Ethernet and wireless) and DNS is configured, we pair our 3G modem into the USB port on the router. Things we need to check the return is the '/ system resource usb'.For devices that are supported Mikrotik, usually a new USB device will appear automatically. Mikrotik also will build a new interface 'ppp-out1'.PPP Dial-OutTo enter the Username, Password and APN from our provider, our input interface ppp-out1 that have been made by Mikrotik.
NAT Masquerade
The last step, we have to add srcnat masquerade for ppp-out1 interface so that the client can access to the internet.Note: Make sure that the modem you are using is sikenali by Mikrotik OS. A complete list of modems that have been recognized by the OS Mikrotik at:
MikroTik RouterOS is based on Linux. Following that fact and knowing that Linux has the live USB versions, I decided to try to install RouterOS on a USB flash drive.The purpose of such installation could be testing, the live demo system or to use this flash drive instead of hard disk in ye olde computer.

This will allow you to restore/re-install RouterOS at a later time using Mikrotik's NetInstall. If you cannot connect to the RouterBoard RouterOS on a LAN port, try resetting the RouterBoard to its default settings: that will ensure you can connect using the ether1 port. You will need an empty USB stick. Run the tool from Windows 7 or later, choose the ISO image you want to use and let the tool do the rest. You can’t use Rufus for this task, as Tiny Core Linux has a specific directory structure on a CD and generated live USB drive. Anyway, if you’re more interested in this process, use the comment section.
