ESXi 6.7 new install, CentOS7 VM, can't access externally from network

Installed as the title states, I cannot ssh thru the ESXi host to reach the internal CentOS7 VM from the external network using a 3rd external IP on the same subnet as the ESXi host and the VM.

Ssh is running on both the ESXi and on the VM CentOS7, but no login prompt and a port scan of the VM shows port 22 closed.

The external workstation, the ESXi host, and the VM all reside on the same subnet.

The vSwitch topology:

vSwitch0

2 Port Groups

•      Management Network VLAN ID0
•      VM Network VLAN ID0
•      both share the same vmnic physical adapter vmnic0

Everything installed with defaults.  What am I missing to make the VM externally available outside of the ESXi chassis?

Thanks!
