How to ignore DHCP requests without Option-82

[Alp Eren Kose]

Hi,

I have got problem which might have an easy answer but I couldn't find it.

What I want to do is to make DHCP server ignore requests without an
Option-82 information. That means to drop the requests without sending a
DHCPNAK, I have got the following configuration however it sends a DHCPNAK
for requests. Does anyone have an idea?

class "with-opt-82" {
  match if( exists agent.remote-id );
}

subnet 192.168.52.0 netmask 255.255.252.0 {
  option routers 192.168.52.1;
  pool {
    failover peer "failover-partner";
    allow members of "with-opt-82";
    default-lease-time 9000;
    max-lease-time 9000;
    min-lease-time 9000;
    range 192.168.52.21 192.168.55.254;
  }
}

Thanks in advance.
