Subject: Quick iptables help
I haven't taken the time to understand iptables and now I need to write a
few rules.

- Computer has 3 NICs: eth0 eth1 eth2
- I want to add the rules to /etc/rc.d/rc.firewall.local
- Rules are:
-- drop everything from eth0 to eth1
-- drop everything from eth1 to eth0
-- allow everything from eth1 to eth2

Anyone have any sample rules to share that will speed my learning? In
other words, anyone want to write the rules for me? ;^)

Alan
