In the latest rolling release, I found that the desination NAT firewall rules were not working. Documentation says to create the following firewall rule:

foreach ($list as $item) {

set firewall ipv4 forward filter rule 10 action accept
set firewall ipv4 forward filter rule 10 connection-status nat destination
set firewall ipv4 forward filter rule 10 state new enable

  work_miracles($item);
}

However it didn't seem to work. I manually created the firewall rules and all of my DNAT started working. I had this configuration in a previous rolling release so this is a loss of functionality.
