Hi all
I've been thinking about using CentOS on a Dell R200 server and turn
it into a firewall / network monitor / traffic shaper in our
datacentre, instead of using a dedicated firewall device.
One of the devices that I have been looking at, with my limited
budget, is the D-Link DFL 860 -

It provides AV, SPI, VPN, DOS, P2P, etc protection. Most of this can
be done with Linux as well, but I'm not 100% sure about the AV part.
How will I use / setup CentOS to check all traffic coming in & out
(HTTP, SMTP, POP3, IMAP, etc) for virusses and clean them? We host
both Windows & Linux servers, and I'm not too worried about the Linux
servers, but Windows needs a lot of extra protection.
well, pop/imap shouldn't need any virus scanning, that would be
handled at the SMTP transfer layer, by something like MailScanner +
ClamAV (I've used this combination), or spamassassin+clamav, and others.
http virus scanning can be done by using Squid as a transparent web
proxy agent and squid plugins. I've never attempted this myself, so I
can't give you the exact recipe.

I'm actually looking todo this on the network layer, rather than the
software layer. Is this possible with Linux?
