TLDR: You don't have to change anything more. You could also input your quad dns server in system - settings - general and uncheck using the ISP dns servers again if you want.
For anybody that comes after: Using wireguard with hostnames and forcing the OPNsense to be a DNS client to Adguard itself can be a bad idea due to race conditions during boot.
There is no selection system - settings - general and uncheck using the ISP dns servers again if you want.
You cannot view this attachment.Do you mean untick the selection Allow DNS server list to be overridden by DHCP/PPP on WAN then I put the empy line on DNS server 9.9.9.9 ????
and use gateway?
