OK, so ShutterSnitch is fully reachable in infrastructure mode. And it sounds like it's the ad-hoc connection to/from the WT-5 that fails.
Could you tell me what your settings are for the static IP, subnet mask, and router? (point 3b in the guide
Double check that the static IP is the same for the FTP server in the WT-5 setup. While you're in there, double check that the port is 26000 and that the username and password is correct.
If things should have gone bad in the iPad wifi network settings, you can try tapping the "Forget this Network" button (again, point 3b in the guide
)) and reconnecting - remember to set up the IP details again.
