simple routing question
Ok i currently have the following setup
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.
[4 port Hub]

| | \_________ [Desk 2, Win98]
| \_________[Laptop, Win 98]
\________[Desktop 1, Win 98]
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.

What do you use? ipchains or iptables?
January 17th, 2002, 01:46 PM
i'm on a 2.5.X kernal so iptables would be nice
January 17th, 2002, 01:49 PM
oops, that should be 2.4.X

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)

Yup. So you've got time after all
