Recommend firewall for CentOS

Any recommendations for a firewall for a CentOS 6.4 server?

CentOS already comes with one that works well. iptables. It's what i use. Pretty much all linux distros have it. It's like the industry standard.

It can be managed with webmin.

I may use iptables.  I was looking at the ones that can do a bit more, examining packets etc.  Installed one that took my server completely down; that is one way to secure a server LOL, prevent ANYONE, including the admins, from being able to access it.

If you really need too secure, too good firewall you will need a hardware firewall.

For me iptable is fine

Yes, I contacted the company I am leasing the dedi from but can not afford the fees at this time.  I think I will just go ahead and set up iptables.  I am not sure what happened with the one I installed, I had it on the minimum default config and just wanted to test it out. 

iptable should be enough, unless you are target of some people.

try this,

Yep, that is the one, took the server completely down.  No thanks.

CSF is a free frontend for IPTables. In other words you can use IPTables without CSF but not the other way around.

IPTables + CSF + mod_security is hard to beat.

If it is just a frontend, then shouldn't that be iptables + mod_security is hard to beat?  I am just going to set up iptables using the command line.

 I like CSF so in my opinion IPTables + CSF + mod_security is hard to beat.
