I need to open ports on a firewall, so that a client can access his VM console through vCenter server's Web Client. I had a look at this page about port description, but I am a little confused.
I already have a port open for the client on a firewall, to access vCenter server's 443 port (https), 9443 (for vSphere PC client), 902 (TCP/UDP) and the client still gets some kind of error related to 902 port being blocked.
Do I have to open port 902 on ESXi hosts and not on vCenter instead? What should I permit as well?
