but it is not actually here to talk about it but to give the settings ICS (internet connection sharing) usb modem in ubuntu manually with some other computer, 2 or more PC.

After the USB modem has been connected to a computer and the driver was install here are some steps for internet connection sharing in ubuntu manually:

1. Open a terminal sign as root and type the command:

gedit /etc/network/interfaces

Fill with the following text below, In my computer my ethernet is 1 so i setting that to eth1 not eth0

auto eth1
iface eth1 inet static
address 192.168.0.1
network 192.168.0.0
netmask 255.255.255.0
broadcast 192.168.0.255

2. Restart your network type in terminal with command below:

/etc/init.d/networking restart

so the result is; net.ipv4.ip.forward=1
and then save.

5. Activate that setting above with type command below :

And the result like this "net.ipv4.ip_forward = 1" without the quotation marks
6. The Next to check IP forward was aktive Type command below :
