If you have a Mac, a UPnP/NAT-PMP compatible router and Remoter VNC 3.0 (or higher) with the RemoterFusion (or Complete) add-on, you can now simplify your setup, and add audio redirection easily with RemoterFusion.
RemoterFusion keeps your information private, all traffic from RemoterFusion to the server is done under an encrypted link.
