How do I save the iptables

Question

I am new to Linux. In CentOS 6.3 I added this rule:

iptables -I INPUT -p udp --dport 9494 -j ACCEPT

Now I am trying to save it:

/sbin/service iptables save It gives me: [FAILED]

I tried to do: /sbin/service iptables stop but it gives me FAILED on unloading modules iptable_filter iptable_filter [FAILED]es

"new to Linux" doesn't really fit the subject matter of Server Fault. unix is a better place when you're first starting out.
@AndrewB - that is absolutely inaccurate. Serverfault has no requirement that site users be of a certain skill level. The only requirement is that they are performing these duties as part of their profession. Even new linux admins are professionals. If you don't care to answer simple questions, than feel free to ignore them.
@EEAA I apologize then, I appear to have picked up a false impression from watching others. The point is fair, there was nothing to indicate a home setting, so it was an inappropriate assumption.

You run:

$ iptables-save > /path/to/file

That will store the current iptables rules in /path/to/file.

Then to re-load the rules:

$ iptables-restore < /path/to/file

OK, I added rules to file /etc/sysconfig/iptables and it worked

	If by "it worked" you mean "it still isn't automatically saving your tables but it's enough", then yes. That's not an answer to the question you posed though. – Andrew B Feb 27 at 3:57
	Well, I don't know what is good enough and what is not! If it works, it should be good? – Andrew Feb 27 at 4:01
	@AndrewB I think the OP is qualified to determine what answer truly answers his question. It's clear that he figured out how to solve the problem and then posted his solution. What's the problem with that? FWIW, I'm giving him a +1. – EEAA Feb 27 at 4:10
	@EEAA respect! Thank you for your help-- I have a lot to learn! – Andrew Feb 27 at 4:12
	@Andrew Right on. Don't let the naysayers get you down. We all started somewhere. Keep the questions coming! – EEAA Feb 27 at 4:13
