ANONYMOUS Port Authority has the potential to be very useful. However, it has a number of quirks.
For example, downloading it and placing it in Applications will result in it hanging on launch. The application needs to be inside a folder named "Port Authority", inside Applications in order to work properly. Also, sometimes it won't accept your password (as in, you can't physically enter it in the password field).
Since it IS still a beta program, none of this should surprise you. If you prefer GUI to the command line, you should give this a try.
