Workstation 9 / Can't ping

Hi there.

I've just finished rebuilding my lab as per this guide: http://boerlowie.wordpress.com/2011/11/30/building-the-ultimate-vsphere-lab-part-1-the-story/ - but I'm unable to ping machines inside the lab.

This is how my machines look inside Workstation 9:

And this how this looks inside VC:

I wanted to check out Log Insight Manager and gave it an IP of 10.0.0.5/24 and the gateway is 10.0.0.1 (DC) but I can't see anything:

I've enabled promiscuous mode on vSwitch0 and 2 within ESXi1 and 2 and I've also set the vLAN to 4095 but still nothing:

Obviously I'd prefer to use the existing DC I built when putting the lab together rather than building one within the nested environment to save on resources so what am I missing?

Thanks
