Summary
There are two methods of accessing the internet from your LeapFrog Pollux Platform device. While both require hooking up to a host PC, you can either using routing, or bridging to make the connection. Either way nets you the same goal. Some differences are Bridging deals with Layer 2 of the OSI model and and allow DHCP broadcasts, while Routing involves Layer 3.
Prerequisites
A Linux host PC
For the Didj, it requires you Enable Networking
Interface Name
- The label you're host PC gave your device's interface, ex, usb0 (as used in this tutorial) run dmesg after plugging in to find what your interface name is, ex. eth1, eth2, usb1, usb2, etc, and replace references to usb0, with that.
Hardware Needed
Routing Method
Configuring the Host
For this tutorial we'll use these IP address.
- Host 10.0.0.1
- Device 10.0.0.2
Configure the host machine's /etc/network/interfaces file as follows as root.
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet dhcp
auto usb0
iface usb0 inet static
address 10.0.0.1
netmask 255.255.255.0
up route add -net 10.0.0.0 netmask 255.255.255.0 dev usb0
up echo 1 > /proc/sys/net/ipv4/ip_forward
up iptables -P FORWARD ACCEPT
up iptables -A POSTROUTING -t nat -j MASQUERADE -s 10.0.0.2
down route del -net 10.0.0.0 netmask 255.255.255.0
down echo 0 > /proc/sys/net/ipv4/ip_forward
down iptables -t nat -F POSTROUTING
To apply these new settings:
On Host
$ sudo /etc/init.d/networking restart
Now you can proceed to configuring your device
Bridging/Routing Method
This is a hybrid method using Bridging and Routing. Configuring the Host
This will require you have bridge-utils installed
On Host
$ sudo apt-get install bridge-utils
You will need to edit a couple configuration files, be sure to make a back up copy first.
Edit /etc/network/interfaces by pasting this in at the end of the file.
auto br0
iface br0 inet static
address 10.0.0.1
netmask 255.255.255.0
pre-up brctl addbr br0
post-down brctl delbr br0
allow-hotplug usb0
iface usb0 inet manual
pre-up ifconfig usb0 down
pre-up brctl addif br0 usb0
pre-up ifconfig usb0 up
post-down ifconfig usb0 down
post-down brctl delif br0 usb0
Edit /etc/rc.local and paste this in just before "exit 0"
echo 1 > /proc/sys/net/ipv4/ip_forward /sbin/iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE /sbin/iptables -A FORWARD -i eth0 -o br0 -m state --state RELATED,ESTABLISHED -j ACCEPT /sbin/iptables -A FORWARD -i br0 -o eth0 -j ACCEPT
On Host
$ sudo ifup br0 $ sudo /etc/rc.local
You can now proceed to configuring the device.
Configuring the Device
If you're using a Didj make you have Enabled Networking
With the USB cable connected to your host, configure an IP address on a different subnet from the rest of your LAN
On Device
# ifconfig usb0 10.0.0.2 netmask 255.255.255.0
Next, add a route from your Didj to the host (making it the gateway) using the ip address of the host's usb0 device.
On Device
# route add default gw 10.0.0.1 usb0
Finally, add nameservers to your Didj's /etc/resolv.conf file (you can add the lines from this example which uses the OpenDNS servers)
nameserver 208.67.222.222 nameserver 208.61.220.220
At this point, your Didj is connected to the outside world - and a ping or a wget to yahoo or google should work.
Todo
Routing packets from the gateway to the Didj.
