[Note: I've started another series of posts using Vyatta in VMware for a more complex environment that starts with this one- crt (2/20/2010)]
After finally getting around to clearing space in the garage and getting an old Dell PowerEdge 2650 I’d acquired up and running with VMware ESXi I started to think about what I’d need to do to set up a few tests/scenarios I wanted to play with. One of these includes the use of Read Only Domain Controllers in Windows Server 2008. Setting up a virtualized Domain Controller (DC) in VMware is easy enough, the trick was trying to figure out how to simulate multiple IP subnets given that I only have one ESX box at the moment.
At work I can do the whole assigning port groups and VLANs thing and let our physical routers do the routing. For my home lab what I needed was some sort of virtual router that didn’t require 1) a bunch of work to configure, 2) lots of resources on my small host. That’s where Vyatta comes in. In addition to their networking appliances they also provide a “Community Edition” of their software as either a Virtual Appliance (for VMware server it appears) or as a Live CD.
I’ve chosen to use the Live CD for my particular lab scenario because it’s much smaller and since it’s based on an ISO image I can have multiple installations/configurations for just the cost of a virtual floppy image for each instance.
Ultimately my goal is to get to a configuration resembling the following diagram all on one physical server:
In this post I’ll describe setting up Vyatta using the LiveCD image and validating that routing is happening.
