Issue with Nested ESXi and Multiple VMkernel Ports

While working with Nested ESXi in my lab, I had an issue where I could communicate with the IP address on vmk0, but after adding multiple additional VMkernel Ports could not communicate with any of the additional IP addresses. It’s a simple network for testing, everything on the same subnet and no VLANs involved. I hadn’t done too much reading on the subject before, other than knowing I needed to implement Promiscuous Mode for the Port Group on the physical ESXi servers.
