Add a second NIC card on the snort box. Connect 2nd NIC to the internal net
with an IP. Make sure your firewall rules don't allow _any_ traffic to the
snort box to pass. Build a read only cable and place that cable on your
stealth interface. Now, your box will be happy, you can connect to it from
inside your net, but no other way.
Hope that helps!
