Firewall port opening vCenter <-> Esxi

[KAD04]

Dear Formers,

I was unable to find a good summary of the exact ports required to be open to guarantee the interaction between vCenter and Esxi hosts.

Is this diagram still accurate for version 6.7: https://www.ntpro.nl/blog/uploads/Screen_Shot_2015-09-28_at_18.38.30.png

This is in the context of having some host in a DMZ to be managed in a vcenter hosted on LAN (hosting basic VMs, no AD deployment...) .

Thanks in advance

I think this is still applicable: https://kb.vmware.com/s/article/2131180

The main and critical ports that must be open for managing ESXi by vCenter server are:

1. TCP 902 for NFC & Client connectivity
2. UDP 902 vCenter Server Agent
3. 443 for vSphere Web Client

Thanks a lot for the resources,

crossing the schema with the port lists it seems some have been changed.
