ESXI vcenter connection behind NAT (Buckeye Hosts)

If you are not familiar with unix or the vi tool, refer here: https://www.cs.colostate.edu/helpdocs/vi.html

Connect over SSH to the ESXi Host and edit vpxa.cfg with vi:

vi /etc/vmware/vpxa/vpxa.cfg

Configure the following settings:

Insert this tag, if you don’t add this tag and restart the services, it will overwrite the IP again with the private one of vCenter:

<preserveServerIp>true</preserveServerIp>

Replace the private IP of the vCenter Server with the NAT'ed one:

<serverIp>192.168.112.29</serverIp>

type :wq! to exit vi

Restart services:

/etc/init.d/hostd restart

Now the connection should stay stable.
