Would be removing many duplicate rules that have to be created in multiple zones. (eg. IP- / URL-Blocklists etc.)
The system checks the floating rules first before any other of “regular rules”.
(As seen in pfSense etc.)
Example / Possible syntax:
set firewall floating rule <1-99999> destination address 1.1.1.1
set firewall floating rule <1-99999> action accept
or
set firewall name Floating-Rules floating-rule
set firewall name Floating-Rules rule 10 destination address 1.1.1.1
set firewall name Floating-Rules rule 10 action accept
