Firewall Configuration with new change
-
@Lakshmana Why don't you use the wan IP of the CentOS box to SSH into then SSH from that to the LAN machines?
-
@thecreativeone91 If this is possible to do?

Right. You can forward different external ports to internal port 22 on different IPs. That's another way to do it.
Don't keep adding new concepts. Let's stick just to getting through his one question. He's confused enough.

It's super easy. So much easier than port forwarding in the firewall. And far more useful.
-
@scottalanmiller Yes Scott I got somewhat confused
-
@scottalanmiller Can you explain Scott
-
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.
