When should you use NSX in manager mode? Hmmm…after running into some issues trying to extend the segments created there leveraging HCX and being told by the VMware support team that they do not actually support network extensions for segments created in this mode…my answer will be NEVER.
Actually, if you have a specific requirement around bridging firewalls, then that may be the only time that you would be forced to do so. Otherwise, please stick to Policy mode and save some headaches in the future.
