Enable/Disable Global zone forwarder is not that good

I'm thinking it might be when a listed this idea but it was not what I was hoping it be

Remove AUTO added DNS as forwarder — Zyxel Community

This is how I want the FLEX H to be

this is what I want to stop from DHCP client interfaces

Yes there is a way to remove the DNS option from DHCP discover/request but really just wanted a simple way USG does not add then to the Global zone forwarder.

What does not having any Global zone forwarder do you might ask? it allows the USG to be a DNS server to do the lookups by going to root server then (TLD) DNS server till it gets to the answer.

Hi @PeterUK

After checking, this still needs the USG FLEX H not request the DNS option in the DHCP discover/request. Let me help share this requirement with our product team. This might be adding an option that disable DHCP request DNS option in each external interface setting.
