Agreed, time to live in the ACL is critical as well .. this is primary
to be used to stop sweeps and penetration testing .. We have SNORT
deployed now but the process is still manual on the back end and of
course does not respond in the time required.

I suppose you could use tcp wrappers to be creative and launch netcat to "bend" the connection right back to the 
originator so they spend all their time hacking themselves.
