[Mailinglist] Internet Connection Sharing

[Sunjith P S]

Hi Binny,

Enable IP forwarding on linux machine:
Run as root: "sysctl -w net.ipv4.ip_forward=1" (without quotes)

To enable it in system startup, edit the file /etc/sysctl.conf and set:
==========
net.ipv4.ip_forward = 1
==========

Now, your windows machine should be able to ping the 192.168.1.5. To enable 
internet connection sharing, add a MASQUERADE rule in iptables:
Run as root: "iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE"

If you want this rule to be persistent across reboots, run "service iptables 
save" after you add the rule.

Merry Christmas.

Regards,
Sunjith
