I'm currently using DroidWall to limit apps' access to the Internet - and it's working great.
Recently I've started to have the need of allowing certain apps network connectivity, but limited only to the current LAN (e.g. only to communicate with IP addresses 192.168.1.x)
DroidWall doesn't seem to offer this in any trivial way (except, perhaps via its custom scripts, for which there aren't any clear instructions for how to apply them only to an individual app).
How can I limit an individual app to LAN access only?
