   It's always been my understanding (but hey, I've been wrong before) that 
if you want the rule applied in BOTH directions, use -b before the -j ACCEPT.

   Remember though, this is coming from a guy that needs to pick up a book on 
firewalls because as hard as I'm trying to understand them, I'm still 
clueless.....
