Is there any security configuration available for use with OpenVPN? For instance, when you have a file share, it would be usefull to scan traffic to stop any virus from spreading to the file server and further. Running antivirus on the server is a must, but it would be even better to stop it before that.
All traffic between client and server should ultimately be encrypted and out-of-view to anything running on the firewall anyway.
I do not know of anything other than squid+clamav for that and it will almost certainly be ineffective for file share traffic.
