Network ports required for backup of ESXi host.

Hi all,

Have tried looking for the answer but am struggling to find consistent information.  We are using BackupExec 2014.

I am trying to backup the VMs on an ESXi 5.0 host.  I have configured the firewall to allow port 902, but am still unable to add the server.  Are any other ports required?

This ESX host does belong to a vCenter, but I only want to directly connect as I will never have the need to backup anything else in that vCenter.

Many thanks

James
