amazing tutorial. one thing i got stack at... how to have on a newly created vmkernel gateway different from that on the management vmkernel (in the video right at the last minute) for Control routable vmkernel.

You will find that changing VMkernel DGW effect other VMkernel interfaces like management as well (so be careful as you might lose connectivity to it). You can just leave it alone and if you test, it should work just fine and even be able to ping the IP from a different subnet. Not exactly sure how it works. I can only guess that it uses proxy ARP.
