stopping viruses with linux firewall

I have a linux gateway with a couple of windows machine behind it. Is there a way to use this firewall to scan for windows viruses on incoming packets.

Frick, I was kind of expecting a tutorial on what the subject says. Next time, please only use the tutty forum for tutorials, as JP mentioned in the Tutorial Forum: READ ME Sticky. Thank you and I'm hoping to see some tutorials from you!

Btw, and I should have mentioned this, but it can be read here..

Hope I helped for future reference.

I hardly think a firewall will scan every packet for evil code.

A firewall would scan for weird network and internet activites. It could detect a dailup from a intruder or a trojan and things but it isn't good for scaning for a virus. Firewalls are mostly good for intrusion detection.

There is gateway scanners available for firewalls and other servers aswell. I advice you to search for content scanners if you want good protection at your border.

You can use software as:
www.pandasoftware.com - "Panda Perimeterscan"
www.mimesweeper.com - "content scanners"

These are only a few of the products available and far from the cheapest available, I mentione them only cause you may get a good idea about what you do want to find and use.

Once again the weakest link in the trail is the human behind the computer, the firewall might detect some viriis/.... but it's got to be the person behind the screen to execute the file....
