Yeah, crickets. I can tell you that a yellow triangle means the rule is invalid because the process path is not valid. For some reason, the app has disappeared from its location.
That's in the help file, which you might want to have a peek at sometime.
Your larger question has been raised a number of times. I've tried answering, always without success. Nobody likes my method, but no one has offered a different one either. One such thread is not very far down the board right now viewtopic.php?f=1&t=6321
So, if you're determined to handle the problem on an individual-connection basis, good luck. When you find the answer, tell us what it is.
Otherwise, I'm happy to try answering smaller questions.
