Sorry for the late responses, have ben really busy for the last couple of days, also due to christmas.
You fill in the public IP for the computer running SAB, CP and/or SB.
That has been asked before, so I'm gonna think of a way to implement a more flexible server setup.
What kind of device are you running? The framework I'm using isn't the fastest unfortunately but I'm working on ways to speed things up a bit. Also when I'm done implementing the SB API things should already improve. (The CP API isn't done yet unfortunately.)
In your setup the ports all have to be set to 80, that's the default HTTP port. I'm pretty sure I'll be adding Headphones support in the future, but you'll have to wait a bit longer for it as I'll first have to polish all the other functionality a bit more.
