| - | * | + | * Restart the network service by running the following command: |

| + | |||
| + | In order to make the computer connected to the openmoko forward packets comming from the interface eth1, it is necessary to enable IP forwarding which is deactivated by default in Ubuntu. It is therefore requiered to issue the following commands with administrator (sudo) priviledges : | ||
| + | * First step: | ||
| + | $ gedit /etc/sysctl.conf | ||
| + | * Second step: look for the following line in this file: | ||
| + | #net.ipv4.conf.default.forwarding=1 | ||
| + | and uncomment it (remove the # caracter if not already done). | ||
| + | * Third step: This change will be effective at the next reboot, or use the following command to make it effective directly: | ||
| + | sudo sysctl -w net.ipv4.conf.default.forwarding = 1 | ||
| + | * Fourth step: it is now time to configure the iptables in order to let the packets go through the gateway (computer connected to the Openmoko): | ||
| + | $ gedit /etc/rc.local | ||
| + | * Fifth step: add these lines: | ||
| + | /sbin/iptables -P FORWARD ACCEPT | ||
| + | /sbin/iptables --table nat -A POSTROUTING -s 192.168.0.202/32 -o wlan0 -j MASQUERADE | ||
| + | where iface corresponds to the interface connected to the internet (wlan0, eth0, eth1, ...). These changes also take effect only after a reboot. To make them effective directly, type the same command in a terminal by replacing '''/sbin/''' by '''sudo''' | ||
