Android and MikroTik

Waiting for a new, miniature MikroTik mAP 2n decided to deal with the possibility of a bundle of Android and MikroTik. As it turned out, all is not too difficult.




I have a source:

• MikroTik RouterBoard 951g-2hnd RouterOS 6.17
• HighScreen Boost Android 4.1.2

It's easier to connect them using WiFi-Tethering, but here everything is simple on Android, enable the access point mode and connect MikroTik to it. It is more interesting to consider the possibility of communication via USB-Tethering.

In general, the work requires RouterOS 6.7 and above and the presence of USB in MikroTik.

What's new in 6.7 (2013-Nov-29 13:37):
*) support Android usb tethering interface;
...

Android smartphone version 2.2 and higher.

• We connect Android smartphone with USB cable to MikroTik equipment.
  MikroTik should identify the device:
  /system resource usb print
  
  It looks like this:
  # DEVICE VENDOR NAME SPEED
0 1:1 Linux 3.3.5 ehci_hcd RB400 EHCI 480 Mbps
1 1:5 Android Android 480 Mbps
  
  
• In Android smartphone, turn on data transfer and USB modem:
  
  1. Settings - Wireless networks - More ... - Mobile network - Data transfer = enable
  2. Settings - Wireless Networks - More ... - Modem Mode - USB Modem = enable
  
  
  Visually

  
  
  
• In MikroTik:
  
  1. In the appeared interface lte1: Add Default Route = enable
  2. Add client to IP - DHCP Client for lte1 interface
  3. In IP - Firewall - NAT add rules for NAT

Through the console:
/interface lte set lte1 add-default-route=yes
/ip dhcp-client add interface=lte1 disabled=no
/ip firewall nat add chain=srcnat action=masquerade out-interface=lte1 disabled=no
