How to Share internet connection in Ubuntu
My home have 3 computer. I want to share internet for all computer.
I search from internet and found Howto Share internet connection from http://ubuntuforums.org.
Following this step and it work!!!!!!
Note: Type all the following commands in a root terminal, DO NOT use sudo.
Start by configuring the network card that interfaces to the other computers on you network:
# ifconfig ethX ipwhere ethX is the network card and ip is your desired server ip address (Usually 192.168.0.1 is used)
My note : My ethX was eth1 and ip was 192.168.1.1
Then configure the NAT as follows:
# iptables -t nat -A POSTROUTING -o ethX -j MASQUERADEwhere ethX is the network card that the Internet is coming from
# echo 1 > /proc/sys/net/ipv4/ip_forwardInstall dnsmasq and ipmasq using apt-get:
# apt-get install dnsmasq ipmasqRestart dnsmasq:
# /etc/init.d/dnsmasq restartReconfigure ipmasq to start after networking has been started:
# dpkg-reconfigure ipmasqRepeat steps 1 and 2.
Add the line "net.ipv4.ip_forward = 1" to /etc/sysctl.conf
# gedit /etc/sysctl.confReboot. (Optional)
After reboot , It's work and I set Windows XP on VMware 2Beta to use this share by set DNS to my ISP.
Everything OK!!!!!
