Can I just leave IPtables to the default setting without any configuration?
Sure... When you installed RedHat, you selected a firewall setting amoung 'High', 'Medium', and 'No Firewall'.
Depending on which you chose you should have essential rules already in place.
To see what rules are currently setup, do....
# /sbin/iptables -L
The output will show your rules for INPUT, FORWARD, and OUTPUT.
Hope that helps, post more questions if needed.... :)
Not Exactly. IPchains is still available at Linux IP Firewalling Chains .Quote:

Although many Linux distros have abandonded it, it is still available in RedHat 9.0, but IPtables is the default.
( see Red Hat Linux 9 Package List . The latest version is version 1.3.10, although last updated 5-Oct-2000. )
Don't get me wrong, I never liked IPchains, and thus never used it going right from ipfwadm to IPtables. Just did not want to confuse people if they come across IPchains which is still in use.
And for the power that IPtables offers over it's predecessors vs. the learning curve, it is not that bad, especially with all the documentation available now, unlike when I started using it when there was none except the man page(s).
But while checking my feeble memory, I came across an interesting item.
Mandrake 9.1 states they feature Kernel 2.4.21 ( see Mandrake Linux 9.1 Presentation & Features . But the latest stable kernel is 2.4.20 acording to The Linux Kernel Archives . The Mandrake 9.1 disk has kernels packakages such as kernel-2.4.21.0.13mdk-1-1mdk.i586.rpm.
What's up with this ???? Are they applying a prepatch and renaming it to the next kernel version???
