On a snort box of mine that connects to the outside world ACID is
reporting bad loopback traffic and the url I am pointed to is below.  
Recomending to setup egress filtering.  

I have used fwbuilder to build my firewall scripts.   

I allow all traffic on my loopback adapter but I do not allow my
loopback out to the outside world from what I can tell.  

How can I confirm that I am not allowing loopback traffic out to the
outside world and that egress filtering is in place?
