Harry:

Using the normal non-inline version of snort, you still have access to
packets on your wire even if iptables explicitly blocks traffic on that
interface.  I can send you specific (sanitized) logs and rules if you
can't take my word for it.

I'm sure this will be asked or told to you a hundred times, but:

If all you want snort to do is look at packets, why did you use
snort-inline instead of snort? did you look at the docs at all?

The whole point of using snort-inline is to use iptables.  It's like
ordering a cheeseburger and then complaining that it has cheese. Go
get a hamburger...

The point is, that snort does not see anything when iptables is
restricting  access to the machine.

I want snort to look at all packages on the interface but iptables still
to  work as a stateful firewall and both at the same time is a little
tricky.
