Firewall ports for esxi to connect to vCenter

[Chris Phillips]

I have a vCenter on one network, and the ESXi hosts I want to manage are on another network, these are separated by a firewall and I have port 902 opened on the firewall.  I'm unable to connect my vCenter to the ESXi hosts but I thought that this was the only port I needed to open - is anyone able to give me a definitive list of which ports need to be open for the communication to work please?  I am having trouble interpreting the list here VMware KB: Required ports for vCenter Server Appliance 5.x

It is the vCenter appliance that I am using

Thanks

Wrong port list you are looking at. These are the general ports you need to have open for inbound to the vCenter.

You want to look at this list, it also specifies direction, source and destination.

VMware KB: TCP and UDP Ports required to access VMware vCenter Server, VMware ESXi and ESX hosts, and other network …

Hi,

I agree with Frank. You ideally need to take that list, filter it into  Excel and then strip out anything for older versions or products that you do not need.

In a nutshell you will also need TCP 80 and 443 as a primary. I'm fairly certain that is the initial connection point from vCenter to the ESXi host.

There might be other ports depending on what services you have.

Regards,

Ryan
