No, you can't change the listen port at runtime currently. As you are
aware, documentation is kind of out of date and volunteer patch is
always highly welcome especially for documentation, either for man page
and our github wiki page.

-b IP is the full syntax. '-b' is used to bind the IP address of NIC you
want to listen to, and '-y' is the option that you want other sheep use
to connect to this sheep.

So in your case, you might need (assume you have 192.168.1.2 to bind) to
set '-b 192.168.1.2 -y 192.168.1.2'

Gateway only sheep means that this sheep doesn't store VM data on this
node at all. It purely function as a gateway to route the VM requests to
other sheep that is supposed to store VM replicated data.

This is always highly appreciated and feel free to edit our wiki (you
simply need to register a github account)
