No, I'm quite confident you don't need any "pass in" rule.

When a "pass out" rule has been accepted, it should go in a "cache" 
table of already accepted connections, exactly like it does now. I thing 
nothing else should change.

Hope someone of monowall development can answer, but I'm pretty 
confident it will work exactly like now.

If I don't go wrong, when the FW goes in checking stage, it checks in 
cache table if connections has already been accepted, otherwise scans 
the rules table. For fw there should be no difference if rule is "pass 
in" or "pass out".
