We need a network filter for porn and viruses.

[powsys]

I need to offer a network gateway to our customers. I would like it to filter out viruses, social networking and porn. Linux based would be cool. Would be nice to load on a refurb Optiplex or Netvista box. Any suggestions?

use opendns and set filters

Here's a site with a small comparison of some different distros. http://www.fsckin.com/2007/11/14/7-different-linuxbsd-firewalls-reviewed/

I've personally used ipcop, smoothwall, pfsense, and a couple of others.

I would use Untangle - a free open source network gateway with loads of features. Google it for more info.

another vote for untangle. great solution and does everything you want for free (excluding the price of the machine)

I'm a big user of opendns but untangle looks promising as well...

 

[MrUnknown]

well, you should definately combine the two.

If you decide to go the "appliance" route instead:

Sonicwall
Watchguard
Barracuda Networks

I've used and sold all, each one has their benefits and weaknesses. I'm personally partial to the Watchguard UTM product line myself.
