I have:

My computer hooked up to the gateway is:

Running Slack with 2.4.18 kernel...
It has 2 NIC's... (3com nic[eth0] and realtek nic[eth1])
eth1'ip is 192.168.0.1/255.255.255.0


My older computer that is just a client is:

Running Slack with 2.4.18 kernel...
it has 1 nic... (realtek[eth0])
eth0 is dhcp'd through the server computer

These two computers are hooked together with a crossover cable

I am looking to share the connection of eth0 on my server with the client computer. I do not want:

A GUI program to do this and
No firewall

I have successfully done this with Mandrake and its DrakConf GUI, so I know the hardware is certainly compatible.

I have tried looking at linuxquestions.org search function and found nothing that I understood and the same with Google.

If you know, what is the best way to get this done?

You won't do this without a firewall. To be more precize, without a program (ipchains/iptables) that can be used also to make a firewall. Simply, tou need masquerading, if I understand correctly.

What you did with mandrake is that you used a GUI to make the firewall rules and those proberly included masquarading.

So use iptables and try to understand what it does so you can easely adapt to changes.

Good luck

There are a lot firewall scripts on the internet. use them.

Thanks for the help... I guess... I'm sure I can find iptables on google ... i was wondering if someone would be willing to give me an idea how iptables works and how i would use in order to make sure my client computer can access the ineternet.

Anyone have a clue? Only interested in answers from those that can help.

Try http://www.netfilter.org/documentati...ials/blueflux/

This helps you out understand iptables..

again... i have taken a look at that and it really makes no sense to me...

if anyone is willing to help me out, take a look at the above configuration i have set up and let me know how this can be done...

If you want to share the pc for internet. Better you use squid as a proxy server. For Squid you have to install squid packeg and following one changes is required in squid.conf file which is basicaly present in /etc/squid/squid.conf.

Just search the following Line.
http_access deny all
and replace it from
http_access alllow all
and restart the squid as
service squid restart.

Still you need some firewall rules then!!
