Iptables..a little help?
 

Hi everybody..
I got a question about iptables...Recently I've been asked to configure iptables for firewall in RedHat 7.1 machine, but the problem is I've never configured ipchains or iptables before, so I'm a bit in the dark about this matter. Do any of u nice people know where I can find a good, simple documentation that an ipchains/iptables newbie like me can follow? I got some links...one of them is a lengthy tutorial from this guy called Oskar, blessed him it's a good tutorial...but quite overwhelming for someone like me. And I dont really understand it..for example, with what kind of options do I have to recompile my kernel?

I hope u all can help me..thanks!

here are some for different configs that you should be able to find a good one in
http://www.linuxguruz.org/iptables/


for redhat you should do this
then using the script that you choose run it to set the firewall rules
( you will need to chmod 755 scriptname to execute it )

after that is done do this

you do not need the downloaded script anymore

the firewall will be controlled by the /etc/rc.d/init.d/iptables script

Thanks for the reply David :)
I'll check out the link...
one more question: do I really have to recompile my RedHat 7.1 kernel (version 2.4). If I do, with what options do I have to recompile it?

Thanks again

no you don't need to as far as I know

You just need to stop ipchains and start iptables. About the configuration... well... if you need to do routing also you can search in google for You can also search this forum for a thread called network config files (or something like that) and there are a few firewall scripts, all quiet good.
