Firewall Configuration with new change
-
Is there a reason that you are using CentOS for this? This is a rather complicated setup that a normal IT pro would not do. Normally you would simply install a firewall product like SmoothWall or pfSense and be done with it. Far easier AND more secure. You should be done in minutes and not need to learn anything new.

@scottalanmiller My manager said me to install firewall with IPtables only

Your manager is an idiot. There is no way around that.
But even still, use SmoothWall, it uses IPTables. So you meet his requirements in a more sensible way. Installing CentOS makes no sense.

@scottalanmiller Ok OK.I need to install the smoothwall in the centos and after that I need to do that.Right
-
When I tried to give the centos machine IP as 192.168.200.40/24 and gateway as 192.168.200.1/24.But the system in VM did not ping after giving gateway in the ifconfig of eth0

It's a pre-built appliance. You'd need to just download whatever Router OS you are going to use and install it.

Not. It's not an application package. (CentOS uses Yum not apt-get anyway) but it's a pre-bulit system of applications, configs, etc.

CentOS uses yum, not apt-get. apt-get is Ubuntu.

http://www.smoothwall.org/download/Exactly. Wipe your current VM and start over. Download a pre-built ISO and install that.

Of which the most common distro is Ubuntu. I doubt he'd be running true Debian. I am aware it's Debian in general. But being that verbose just gets more confusing for a novice, which I do not mean offense by this, but he clearly is.

@thanksajdotcom This smoothwall seems to be ISO file.I need to do that only in CentOS 6.5

Why can you only use CentOS?
-
Several of the questions you have been asking make it seem like you are either a college student, or are just being given busy work by your manager. It really doesn't make a whole lot of sense to only use CentOS 6.5 for this when there are much leaner distributions designed specifically for this task.
One of the things I learned when I started in IT (although I'm still relatively new to this considering some of the other members) was that you should always question the motivation of a task you are given. It helps you learn why you are doing something instead of just the how. Could also lead to finding something your manager wasn't aware of (like Smoothwall or pfSense) and show you initiative to learn and find the best solution for the business.

Why? That wasn't in the requirements that you said before and is just plain silly. Is your manager out to sabotage you and the clients? He seems insane.

In business and psychology circles this is called "thinking at a goal level." You need to not focus on the tasks and forget WHY you are doing something.

His manager is just stupid. He has a way of doing something in his head because he probably heard or read something once and is clinging to something he doesn't even understand. I agree with @coliver. If it's already designed and pre-packagaed for you, why make it harder on yourself?
