When setting up my new USG Flex 200H i cant find the Advanced DHCP functions setting.

The "old" USG FLEX 200 was able to set this function however the H doenst show this function, how do i get this fixed.

I need to set DHCP code 43

Also the option FQDN is missing when adding addresses under object, the device seems not finishend yet

    Hi PeterUK

    Is it possible to set DHCP option 66 via cli command?
    If it's possible, can you send me the commands to configure it in 500H ?

    Since update 1.20 the Advanced DHCP functions are available only not code 43 😵 why? in the normal flex series this works.

    Via the console option 43 is possible 🤪
