Internet sharing from fedora core 4

abdullahcsedu · 03-13-2008, 08:05 AM

Hi all,

I have two desktops at my home. One desktop is connected to internet using broadband connection. I am sharing internet connection from that pc using windows xp. So at the client side i can use internet both at windows xp and fedora core 8. But problem is that on the server pc i use both windows xp and fedora core 4. When i boot at fedora 4,i can't access internet at my client pc. I am a new user of Linux and don't know how to configure this. So please give me idea to share internet connection from fedora 4 to my client pc.

At my server side there are two lan cards. One lan card is used to connect to the internet and the other lan card is used to connect two desktops using wires.

So please give me details information about internet sharing from fedora 4. Please also mention which packages are needed to establish internet sharing.

Thanks
ABDULLAH

The quick and simple way is to edit /etc/sysctl.conf and make this change

Code:

net.ipv4.ip_forward = 1

Then run this

Code:

echo "1" > /proc/sys/net/ipv4/ip_forward

Then turn on masquerading add this to your /etc/sysconfig/iptables

Code:

*nat
:PREROUTING ACCEPT [0:0]
:POSTROUTING ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A POSTROUTING -o <external_interface> -j MASQUERADE 
COMMIT

And restart iptables.
