Part II: Apple iPads, Apple TVs, Bonjour & AirPlay Across Subnets Using Open-Source Software

In my previous post HERE, I gave a brief description of Apple's implementation of the mDNS protocol which they named "Bonjour". I explained why the protocol does not function in a segmented (subnetted) network and described the open-source solution that we deploy for our clients which is comprised of a free, open-source Gentoo Linux (virtual) server running the open-source implementation of the mDNS protocol called "Avahi."

My goal in this post is to describe in detail exactly how to implement your very own virtual "Bonjour Gateway" in a VMware vSphere environment.
