Icecast only ever uses the ports you've explicitly configured it to
use (port 8000, in your case), that's all that will need to be open.

The client port numbers don't matter in this case - they're allocated
by the client itself (actually, usually by the operating system,
pseudo-randomly) when the client starts to connect to the server, but
the firewall won't need those open.
