Hey,

I know I'm just missing something simple and it's probably something I've overlooked but I'm having an issue with a regex in one of my port tests...

This works:

PORT "LOCAL=%[\.:](8611|8621|8631)$" state=LISTEN

But this doesn't...

PORT "LOCAL=%[\.:]86?1$" state=LISTEN 
6? matches zero or one 6, so that is not what you want.

6. matches a six, followed by any character
6[1-3] matches a 6 followed by a one, two or three.

So you want:
PORT "LOCAL=%[\.:]86[1-3]1$" state=LISTEN

HTH,
Paul
