Hello Everyone after done working with Linux Web server, I am now planning to Set up a Linux Firewall.
This firewall will be used in our Company Basically, just for only more than 15 computers.
Any advise on how will i get started?
Can i set up this using our Old Machine?
Thank you in Advance:)

I think the community would suggest using CentOS. Here is a good guide that will help you get started with IPtables. http://wiki.centos.org/HowTos/Network/IPTables

Thank you for the reply. We already have a Centos installed in one of our old machine at work. I will Check this things tomorrow.

You certainly can do a normal OS like CentOS or Suse. But a firewall appliance OS will likely be far better.

I guess a good spot to start is do you have a budget or are you trying to use old hardware and free software to accomplish this.

If Linux is a necessity, Untangle is the most common product found in the SMB. But it tends to be too complex for its own good. We used to use SmoothWall long ago, they were good.

The big leader in this space is not Linux but FreeBSD with pfSense. PfSense is generally considered the best of breed for this role.

I've also heard a lot of good things about untangle.

I've been using the open source Smoothwall Express for well over 10 years and love it. It's Linux based and quite configurable, but runs straight out of the box. It's never let me down. Download the ISO, boot an old PC with 2 NICs, tell it which NIC is on the internal side and which is on the external side and it installs. Once it is insalled, you logon to the web interface and use the GUI to configure it (such as opening ports, viewing logs, setting forwarding rules). We have it running as a virtual machine. There is a corporate edition, which isn't free but offers lots of additional features, like VPN. We used the corporate edition for a while but have now gone back to the free edition.

Mostly, I think, that is because of their marketing. It's a rather weak product overall. Way too complicated and weird for its own good.

@Carnival-Boy NTG ran SmoothWall for years.

Definitely very easy to use. We had the commercial version back then. They are still around and offer free versions plus commercial support options too.

I will recommend pfSense as a firewall/router or Vyatta.

Is Vyatta open source still being maintained? Since Brocade bought them they seem to have gone silent.

We've been using ClearOS in our branch offices for almost 4 years. http://www.clearfoundation.com/Software/overview.html

Pretty straight forward and easy to manage using the web interface.

I loved ClearOS prior to version 6. I gave up on it after that.

scottalanmiller

I've heard good things about ClearOS but have not used it myself. Being built on a base of CentOS is nice.

Good morning. Pretty much all of the options here are free. So you have a lot to choose from.
