Hi @pavelgl , thanks for syntax obs. I've forgot to mention that i have observed that the syntax proposed in the post was different from the guideline, and I already tried like posted.
Just did again:
config mac 'wg0'
option Mac 'mac_address_iPhone1'
option networkid 'wg0'
list dhcp_option '6,162...57,149....92'
Still getting DNS leaks...
