Linux antivirus gateway

[Chong Yu Meng]

Hi all,

I'm looking for information about setting up a Linux box that acts as a 
antivirus gateway -- i.e. scans and cleans viruses at the network edge 
before it has had a chance to infect computers within the network. So 
far, a Google search turned up BitDefender and ClamAV.

Unfortunately I only have a old Sun Netra T1 box available to install 
Linux and the AV firewall package on. I had to jump through many, many 
hoops just to get Aurora Linux installed (because of the unique 
architecture of the Netra T1), and I don't want to have to do the same 
for BitDefender, which runs Debian (does Debian have a Sparc-based 
distribution?).

As for ClamAV, I thought that this is for Sendmail scanning only. Am I 
correct? Or can it scan traffic that is entering the network too?

Any help would be deeply appreciated!
