Internet access for Kindle via USB

Setup on Host PC

Add the following to /etc/network/interfaces

 iface usb0 inet static
    address 192.168.15.201
    netmask 255.255.255.0
    up echo 1 > /proc/sys/net/ipv4/ip_forward
    up iptables -P FORWARD ACCEPT
    up iptables -A POSTROUTING -t nat -j MASQUERADE -s 192.168.15.0/24 
    down echo 0 > /proc/sys/net/ipv4/ip_forward
    down echo 0 > /proc/sys/net/iptables -t nat -F POSTROUTING

Note: This should be replaced by some udev rules to make it work even if usb0 is already in use.

Setup in Kindle

echo "nameserver 4.2.2.1" > /etc/resolv.conf
route add default gw 192.168.15.201
