Hi, I need a firewall software which will block social websites and shopping websites for our small scale industry. previously i had a centos configured firewall with linux ubuntu server, due to the on board lan failure and the pci slot too failed i am unable to use the lan port or the pci add on port to configure back my firewall through the same. So i planned to manually install a firewall software in all pc to block internet usage, any suggestions kindly let me know. I have already used zone alarm and comodo softwares but not happy with those. As i am a newbie with this kindly help me with procedures. I want to access lan connected to my linux  server and only need to block the above mentioned websites other than that i need internet connection for our outlookmail, kindly let me know how to configure so. Thanks in advance.

Since this is for a small scale industry, it would be better to replace the faulty board and get your CentOS configured firewall back up and running. It'll be way easier for you to block websites that way, rather than installing and maintaining a firewall on every single computers (as the protection could be easily bypassed).

I would use a old PC and install IPCop, then use proxy and configure it to filter the list you supply, it will then block access to them sites.

You could also look at Untangle.

You could also add open DNS to your router and then you'd be able to create your own custom block list, Of course you'd still need a firewall.

I would definitely recommend a site firewall over trying to install and configure something on every PC. Either repair your current PC, or find some other hardware to re-purpose. My personal recommendation would be to look at PFsense, but there are a ton of free and open source options out there.

Agreed with all, a $100 beater box used computer with twin hardware lan cars is dirt cheap and remake your ege-firewall, i find p4 3000mgz PCs or AMD k7 2400mgz pcs 1gig ram in trash cans on the side of the road offten, sometimes i find better.


as well a T100 old stile lan card is still 100Mbps so should be fine speed wise, i tend to like the old hardware 3com cards my self.


And as meny pointed out you have options when it comes to ege-firewalls/router setups for older computers in linux, and from my reserch meny are as good or better then $1000 hardware firewalls and way cheaper.
