Use Linux sever as virusscanner/bridge
I am working on a security solution for a large company. They want more than just a standard firewall towards internet.
What I am planning to set up is a Linux PC with two network cards. One for WAN and the other for LAN. The idea is that all traffic will be routed trough this server (by bridging the cards).
The idea is to virus scan all data that passes through the server. I am no Linux expert, so I have two questions related to the solution:
1. Is there any antivirus software that can be installed on a Linux OS, that recognize viruses that attacks Windows OS?
2. Is it possible to configure this program to scan files that just passes through in realtime?
