View Full Version : [SOLVED] Easy Internet connection sharing with firestarter.

October 17th, 2009, 03:32 AM
So I wanted to hook up a windows laptop to the internet this way:

internet -> wireless (wlan0) -> linux desktop -> wired (eth0) -> windows laptop

and found this guide (https://help.ubuntu.com/community/Internet/ConnectionSharing)

but wanted to use a easier way. Well I found it after some effort, so I thought I'd post how I did it.

first install firestarter

sudo apt-get install firestarter

then give your wired connection a ip

sudo ifconfig eth0 address

(I did this because firestarter would give me an error about eth0 not being ready)

(I choose because I was going to use, but when I did I couldn't use the internet, the cause: my modem is, the solution: use something else)

run firestarter

sudo firestarter

run the wizard. first choose wlan0 and dhcp. click next choose eth0. next. save.

Now set up the laptop.
(connect it with either a crossover cable or connect the desktop and laptop to a switch)
in windows go to the network connection properties.
under tcp/ip properties set to manual.
ip of
gateway of
mask of 255.255.255
dns primary of
secondary of

and now you should be set up.
comments welcome.

I found that I had to assign the IP to eth0 using:

sudo ifconfig eth0 got rid of the error saying my eth0 was not ready. But now I get a more general error.
