As I understand it, vCenter does not support the NAT method. I need to connect approximately 20 ESXi hosts from different countries to the vCenter, and each ESXi host has one public IP address. I could only find two methods to solve this problem:
Moving the vCenter over the network and assigning it a public IP address.
Installing a router as a virtual machine on each ESXi host to access the ESXi hosts over the private network (since I do not have access to the physical router of the ESXi hosts).
Both of these solutions come with numerous difficulties and potential security issues. Do you have any other suggestions for this challenge?
