Simple Net Sharing

[Igor Maciel Macaubas]

Hi,
Yes, you have to change your gateway and DNS configuration on your windows
machines.
Put the IP adress of your linux machine as the gateway in windows machines,
and add this line in your rc.local file (in your linux machine):
echo 1 > /proc/sys/net/ipv4/ip_forward
You can run a DNS-caching-only server in your linuxserver too, and configure
your windows machine to use your dns.
And that's all.

Best regards,
Igor
