Not quite but it is related. &nbsp;The ICMP is being blocked by an ASA, my problem is making Veeam SureBackups work. &nbsp;I get an NFS mounting error when the lab loads and it was suggested there could be a communications problem which I'd like to investigate. &nbsp;I'll give it a try now, thanks.

So previous question caused by ASA!

I think so but I wasn't too concerned by pings, just the list of ports Veeam and VMware need open to talk. &nbsp;I disabled the firewall and have the same problem so off to make another post. &nbsp;Thanks for the help hanccocka!

<div class="content wysiwyg-content">
I am testing a problem application where the root cause may be related to blocked ports. &nbsp;I'd like to completely disable the firewall on one of my ESX host servers using this command:<br />
<br />
esxcli network firewall set --disabled<br />
<br />
Is this possible to do during the day or would I chance interrupting communications as would happen disabling the firewall on a windows server?

Disable ESXi firewall for testing during production?

VMware, a software company founded in 1998,  was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies.

VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture.  Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.

Software firewalls, also known as host-based firewalls, provide a layer of software on one host that controls network traffic in and out of that single machine. Most operating systems now include firewall software, but many available software firewalls include central distribution, antivirus systems and disaster recovery.
