Thanks for making PortKnocker available both free and open source. I have a feature request.

There are some Android apps (eg aNag) which regularly want to contact a host which may be behind a firewall (eg your Nagios server at work). Port knocking is a great way to tell that firewall who you are and get it to allow access from your IP.

You want to run apps like aNag all the time so they can give you alerts, so they're constantly usable, etc. but you can't do that because your phone's IP may change a lot and you will lose access until you re-knock.

THE FEATURE REQUEST: It'd be handy to mark a knock entry to indicate it should re-knock every time your phone's IP changes. So effectively your knocked access follows you around as your phone hops networks.

If you're looking for a value-add feature that you can charge for over and above the features in your free version, I think this might be a good candidate. (Similarly, being able to set what app is launched after a knock would be something worth charging for.)
