Appendix A: Configuring Your Firewall
Firewalls on your computer often cause connection problems for Squeezebox
Duet and other network devices. While it is not necessary to disable your
firewall in order to allow Squeezebox to communicate with your computer,
temporarily disabling it can be a quick way of diagnosing the problem.
If turning off your computer’s firewall allows Squeezebox Duet to connect
to SqueezeCenter, you should turn it back on and configure it to allow
communication on the following ports:
Port 3483 (UDP)
Port 3483 (TCP)
Port 9000 (TCP)
Logitech Technical Support can provide assistance with configuring the
firewalls built in to Windows and Macintosh OS X.
Note: It is not necessary, or even desirable, to change the firewall settings
on your router to use Squeezebox Duet unless your current firewall is
configured to limit access only for specific local hosts. Consult a network
professional if you are unsure of how to configure your network properly.
