simple routing question
Ok i currently have the following setup
Code:
[Internet]
|
|
[Linux]
|
[4 port Hub]
| | |
| | |
| | |
| | \_________ [Desk 2, Win98]
| \_________[Laptop, Win 98]
\________[Desktop 1, Win 98]
The the Linux has eth0 running to the outside world on DHCP, though the ip is pretty constant and only changes if the box is down for 3+ days. The hub is on eth1 with a fixed address of 192.168.0.1.
The other three machines are .2 (desk 1) .3 (desk 2) .4 (laptop) in the 192.168.0.X range.
What i need is some simple routing rules that will allow my linux box to contine to be a functional server, while allowing the 3 machines inside the localnet to access the web, irc, ftp ect.
I understand the basics of the rules, but i'm short on time at this sec so i'm not able to write my own from scratch. If u can give me some help i'd apreciate it.

I'm not sure (never used iptables), but I think this is what you're looking for.

hmmm, how does this sound:
i turn ip_forward on, set the FORWARD chains policy to deny and then make a rule that accepts everything from eth1 (localnet)
