Just curious, any reason you want or need VMTools for this appliance? I've run IPCOP standalone (not as a VM) and once installed, I've never had to access the console. Administration, logs, etc, all done through a web interface. Thus I'm confused as to what advantage the tools would give you?
Alternately, you could just make your own IPCop VM and install tools yourself. Installing IPCop is extremely simple. Just download from www.ipcop.org. I installed mine in less than 30min.
