Include Windows clients into a separated address pool

[tumbochko]

Hi everyone.

I wanna include Windows clients into a separated address pool.
If I understand correctly, it is possible by usage of following instruction:

Code Select Expand

class "ms-dhclient" {
match if substring (option vendor-class-identifier,0,4) = "MSFT";
pool {
option domain-name-servers 1.2.3.4;
range 1.2.3.10 1.2.3.200
}
}

How to correctly add this instruction into DHCP/OpnSense configuration?
