Thank you so much for the script, is there a way to modify it to open all ports upward from 500-57000. I'm running ESXi and would like to use

5000
57000

ESXi 7 isn't loading my custom settings despite creating a custom XML which I placed in /etc/vmware/firewall/. I'm not too sure what am I doing wrong.
I'm running a bunch of containers on top of my ESXi and don't want to deal with create a custom.xml for each port required.
I rather just disable the firewall all together but it's not doable.

You should be able to modify begin/end to the port range that you are looking for. It may be blocking you because 49152-65535 are generally reserved for client devices on the network. Can you share your config?

I figured it out. Thank you so much for getting back to me. Its the darn VBS even though I unchecked it and thought I removed the settings off of the VM, I was still persistent. I had to rebuild the VM and that resoled my issue.
