Well when it came to getting the server installed between other obligations and my desire to do it right I’ve resolved myself to the fact that I’m actually going to have to plan this setup out. I was able to get the networking the way I wanted by creating a “multihomed” interface bridge connected to eth0. Each tap is set to its own vm and each vm configured its address statically. In order to route to this device I configured a virtual interface on the bridge on the same subnet as each tap will be. I will protect this network with firewall settings and using the appropriate forwarding rules manage what external ips expose what ports to what guest. I could think of other ways of handling this but for me managing this compartmentalized setup is more straight forward and less prone to me getting pwned once I go live.

Here is my pretty picture to help me keep things straight. So far everything seems to work fine and I even was able to pull up a backup of this site without issue. My main concern speed is a non issue, moving from a 1Ghz with 256MB of ram to a dual core 3Ghz system with 2GB of ram is plenty to run all three oses faster than I was running the one machine before.
