Create Persistent Custom Firewall Rule on ESXi 6.5

Hi Guys,

Just wondering if anyone here has successfully created persistent custom firewall rules for ESXi 6.5. I've reading up on this and seems the only supported method id to create a VIB using a depricated http://labs.vmware.com/flings/vib-author

I've also read many blogs which kind of explain the process, in particular the one authored by William Lam

http://www.virtuallyghetto.com/2011/07/how-to-create-custom-firewall-rules-in.html

Now for my question.. Is this still the only supported way of doing this, I'm also confused because Willian shows an example of creating a new firewall XML virtuallyGhetto.xml, How was he able to load this XML as far as I can sell the firewall only load service.xml

Any tips or help would be much appreciated?
