isc-dhcp and wds

[pumbos]

Good day.
I set iPXE on nix(debian+tftp+apache), set options in isc-dhcp

Code:

host clientname2 {
   if exists user-class and ( option user-class = "iPXE" ) {
   filename "http://192.168.0.1/boot/menu.ipxe";
} else {
     filename "undionly.kpxe";
  }
  server-name "ipxe";
  next-server 192.168.0.1;
  hardware ethernet 2c:56:dc:4d:fa:8f;
  fixed-address 192.168.0.69;
}

And its works!
But if i start WDS server in same subnet (192.168.0.2 for example) - and NO options for in it DHCP config at all - all pxe clints starts boot from WDS.
what's wrong with is?[/quote]
