I expect you have ONE PC with TWO ethernet cards(interfaces). One goes to the other computer and one goes to the Internet.
Example situation:
[font:Courier]eth0[/font] - to 2nd computer, IP 192.168.0.1
[font:Courier]eth1[/font] - to Internet, IP 10.64.1.99
Let's do this on the computer in console (as root):
[font:Courier] echo "1" > /proc/sys/net/ipv4/ip_forward [/font]
(or permanently, add this line to [font:Courier]/etc/rc.d/rc.local[/font]
OR set it in [font:Courier]/etc/sysctl.conf[/font] (esp. in RH/Fedora))
[font:Courier]/sbin/iptables -t nat -A POSTROUTING -o eth1 -j MASQUERADE[/font]
Then, on the 2nd computer, you have to:
- set default gateway to 192.168.0.1
- set up the same DNS servers as on the 1st computer
You may enter fixed IP as well (eg. 192.168.0.2) or keep it on DHCP.
I have just set up this succesfully. If I didn't write something clear, you may ask me at: brozkeff-AT-gmail-DOT-com
