= Network Sharing =

With Maemo PC Connectivity, you can easily set up an Internet connection and share it from a Maemo device to a host PC or from a host PC to a Maemo device. For sharing a connection from a Maemo device to a host PC, you should configure from which interface (WLAN, USB or Bluetooth) the Maemo device accesses the Internet and share it with other interfaces (WLAN, USB and/or Bluetooth).

= Sharing network from Maemo device =

To share a network connection from a Maemo device to a host PC you need perform these steps on the Maemo device:

* Run '''Settings - Control Panel - Connectivity - PC Connectivity Manager'''.
* Click on the '''Advanced''' button.
* Select the '''Internet''' connection type, figure [[#fig:pc_connectivity_network_sharing_mpc_maemo_nm_internet_sharing|4.1]].
* With the '''Connect Using''' option, you can choose from which interface (WLAN, WLAN adhoc, USB or Bluetooth) the Maemo device accesses the network.
* With the '''Share internet connection with''' option, you can choose the interfaces (WLAN, USB and/or Bluetooth) with which to share the Internet.
* Click on the '''Apply''' button.

= Sharing network from Linux =

After you have installed the host-pc-connectivity package to your Linux host PC, you can automatically share an Internet network connection from your Linux host PC to a Maemo device.

If you want, you can configure sharing from your Linux host PC manually. Suppose you have an Internet connection through an ethernet cable interface, normally eth0. You can share this network connection with any other interface (USB, Bluetooth and/or WLAN) by executing the following commands:

$ iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
 $ echo 1 &gt; /proc/sys/net/ipv4/ip_forward

You can replace eth0 with any other interface (usb0, bnep0 or wlan0) that has a working Internet connection. To disable network sharing, you should execute the following commands:

$ iptables -t nat -D POSTROUTING -o eth0 -j MASQUERADE
 $ echo 0 &gt; /proc/sys/net/ipv4/ip_forward

If you want to permanently share the network from your Linux host PC, you should edit the /etc/network/interfaces file. For example, you can add the following lines to it to share the network every time the USB interface (usb0) is up.

mapping hotplug
 script grep
 map usb0

iface usb0 inet dhcp
 # commands to enable internet sharing
 up iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
 up echo 1 &gt; /proc/sys/net/ipv4/ip_forward
 # commands to disable internet sharing
 down iptables -t nat -D POSTROUTING -o eth0 -j MASQUERADE
 down echo 0 &gt; /proc/sys/net/ipv4/ip_forward

= Sharing network from Windows =

To share the Internet network from your Windows host PC, you should follow these steps:

* Open the '''Start - Control Panel - Network and Internet Connections - Network Connections''' dialog.
* Right click the interface from which you access the Internet.
* Select the '''Properties''' option.
* Select the '''Advanced''' tab.
* Under '''Internet Connection Sharing''', select the '''Allow other network users to connect through this computer's Internet connection''' check-box, figure [[#fig:pc_connectivity_mpc_win_internet_sharing|4.2]].
* Click on the '''OK''' button.

= Sharing network from Mac OS X =

To share the Internet network from your Mac OS X host PC, you should follow these steps:

* Go to '''System Preferences''' and click on the '''Sharing''' icon, figure [[#fig:pc_connectivity_mpc_mac_internet_sharing_preferences|4.3]].
* Select the '''Internet Sharing''' service.
* From '''Share your connection from''', select the interface that has an Internet connection. For example, ''AirPort'', figure [[#fig:pc_connectivity_mpc_mac_internet_sharing_properties|4.4]].
* From '''To computers using''', check the interfaces you want to share the Internet with. For example, '''Bluetooth PAN'''.
* Enable the '''Internet Sharing''' check-box.
