A quick tutorial on giving a BeagleBone Black Internet access from a computer.
This is a quick tutorial on how to tether the BeagleBone Black (and other Linux devices) to a Linux computer for Internet connectivity. By default, the BeagleBone Black will take
192.168.7.2 as its IP address when connected to a computer via USB. We need to assign
192.168.7.1 to the USB Ethernet device (
enp0s25 in this tutorial) and route all outbound packets to this device from the BeagleBone Black to the Internet via the wireless device (
root (or using
sudo) on the computer,
$ ifconfig enp0s25 192.168.7.1 $ sysctl net.ipv4.ip_forward=1 $ iptables --table nat --append POSTROUTING --out-interface wlp3s0 -j MASQUERADE $ iptables --append FORWARD --in-interface enp0s25 -j ACCEPT
root on the BeagleBone Black,
$ route add default gw 192.168.7.1 $ echo "nameserver 22.214.171.124" >> /etc/resolv.conf
This tutorial can also be adapted for tethering other Linux devices to an Internet-connected Linux device, but IP addresses and device names may be different.
