How do I set-up a firwall without NAT w/ iptables v1.2.8 - kernel 2.4.22?

I am running Slack 9.1 with kernel 2.4.22. I have previously setup a firewall on a redhat box using iptables, worked fine; however I was using network address translation. I would like to create a firewall that will not use network address translation. I thought all I would have to do would be to

1. configure two network interfaces on the same subnet.
2. echo 1 >/proc/sys/net/ipv4/ip_forward.
3. Apply rules, etc...

I have enabled forwarding, there are no rules, the FORWARD policy is ACCEPT. However packets will not forward through the box, from a seperate machine that can see eth1 of the "firewall" i can see eth0 of the "firewall" but i cannot see past this interface. What might I be over looking?


p.s. - are there any slackpacks of iproute2 or iputils?
