How to share internet


I have 2 computers 1 linux redhat 9 and one windows computer. I have an ethernet switch and i also have 2 lan cards in my linux computer. i have everything set up and my local area connection is working fine, but i want to get on the internet with my windows computer.

My friends says i have to somehow enable share internet on the linux mashine, but he uses mandrake and does not know where this option is on redhat 9

so my question is, can someone tell me how enable share internet on linux redhat 9.0. or if that is not possible, how i could actually connect both computers to the internet using 2 lan cards and a switch (i actually have 3 lan cards if you count the one in my windows computer)

thanks already in advance

hi,

you have to use IP forwarding and Masquerading

try the following link: "http://www.linux.org/docs/ldp/howto/Masquerading-Simple-HOWTO/index.html"
for a made simple howto

and the TLDP howto "http://www.tldp.org/HOWTO/IP-Masquerade-HOWTO/index.html"

Code:
echo "1" > /proc/sys/net/ipv4/ip_forward
iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE
That's what I use. I'm dial up for you'll probably need to modify it.
