For some odd and unknown reason, the Eset firewall will often throw an alert about an insecure firewall rule in reference to the built-in equi rule. It usually occurs after an in-place Eset upgrade to a new version. You possibly answered one of those alerts as a block action which resulted in the rule being disabled.
What appears to be triggering this activity is Eset's Application Modification detection which is only applicable if the firewall is set to Interactive mode. Bottom line - this activity appears to be a long running bug in Eset firewall processing.
