As you already have been told, the <- direction has been decapricated.

Even if it was possible, the reporting-tool would have no clue as to if
the matched packet was triggered by a "->"-rule or a "<-"-rule.

No matter how the problem is solved syntax:ally, you need to add new
information to the _alerts_. This information give the reporting tools the
possibility to create correct reports (as described earlier).

So, two things are needed:
* Snort needs to tag the alerts with a reference to the "bad" side
* Reporting tools need to take the new tag into account when
  generating reports that show the worst offenders and the most attacked
