Internet Connection Sharing in Ubuntu 11.04/ Fedora 15

I have a small inetwork in my home. We have two internet connections one wired line and other is my internet dongle. I used wired line most. One day I got stuck with that and decided to share my dongle to all others.

I used a script called Nat script to share the connection in Fedora 14.

Now network manager is there to manage all the network activities in gnome. I know that in gnome 3 it is all the mess. But I tried to share the connection .

It is very easy.

To enable this, you must follow three steps:

1. Install dnsmasq on your computer. (On Ubuntu, you will want to install the dnsmasq-base package.)
2. Make sure your WAN connection [My Internet Dongle] (i.e. Internet-connected connection) is all configured (e.g. with DHCP or a static address) and working.
3. For your LAN interface (which might be a second network card or a wireless card),
4. Open the netwrok manager properties in ubuntu. in Gnome 3 you want to type Alt+F2 and nm-connection-editor
5. select “Shared to other computers” in the IPv4 Settings tab.
6. Click OK.
7. Configure all your other computers in the network to DHCP.
8. For that create a new connection in the network manager and click ok. then connect to that connection in the netwrok manager.
9. It is working perfect.

Nice work with Network Manager. What a great piece of software.
