Is this dialup, cable or DSL?
How many machines are you looking to set up?
If you have a cable or DSL connection, how many ethernet ports are on the modem?
If you have cable, does the ISP assign addresses statically or dynamically?
Knowing youe specific needs will help answer your question.

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 - to 2nd computer, IP 192.168.0.1
[font:Courier]eth1 - 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
(or permanently, add this line to [font:Courier]/etc/rc.d/rc.local
OR set it in [font:Courier]/etc/sysctl.conf (esp. in RH/Fedora))
[font:Courier]/sbin/iptables -t nat -A POSTROUTING -o eth1 -j MASQUERADE
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
