Disable ESXi firewall for testing during production?

I am testing a problem application where the root cause may be related to blocked ports.  I'd like to completely disable the firewall on one of my ESX host servers using this command:

esxcli network firewall set --disabled

Is this possible to do during the day or would I chance interrupting communications as would happen disabling the firewall on a windows server?

Not quite but it is related.  The ICMP is being blocked by an ASA, my problem is making Veeam SureBackups work.  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.  I'll give it a try now, thanks.

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