Persist the firewall rules

http://www.virtuallyghetto.com/2011/08/how-to-persist-configuration-changes-in.html

1. esxcli network firewall set --default-action true
2. esxcli network firewall set --enabled false
3. echo "esxcli network firewall set --default-action true" >> /etc/rc.local
4. echo "esxcli network firewall set --enabled false" >>/etc/rc.local

5. /sbin/auto-backup.sh ----- preserves changes it right away

This firewall might help, if you are having consistent Vcenter Disconnects (vpxa--
vpxd communication)
