ISP temporarily disabling port due to receiving excessive ARP requests from SonicWall.
In the SonicWall URL replace main with diag.
For example, if you have https://192.168.168.168/main.html, it would be https://192.168.168.168/diag.html.
Select Internal Settings.
Under Arp Settings please deselect Enable gratuitous ARP Compatibility Mode.
You also have the possibility here to specify a maximum amount of Gratuitous ARP's per minute with the editable section:
Never broadcast more than (100) Gratuitous ARPs in any 60 second period.
