PXE and DHCP Servers are not on same subnet.

Unanswered Question
Feb 15th, 2010


I have configured the PXE Server with Symantec Solution on Windows Server. The PXE clients that are working on same subnet they are working properly. I have PXE clients working on different subnets, they are using WAN connections but they can’t connect to PXE server.

I receive this error: PXE-32: TFTP open time out

The DHCP configuration that I’m using is:

ip dhcp pool DATOS
   network X.Y.31.0
   bootfile BStrap\X86pc\BStrap.0
   default-router X.Y.31.253
   netbios-name-server X.X.10.225
   domain-name .XXXXX.com
   dns-server X.X.10.225 X.X.37.225
   option 66 ip X.X.10.204

This configuration is not working, do you have any example that is working?, do you have any idea ?.

Thank you, best regards.

I have this problem too.

If they are not in the same subnet, then try adding "ip helper-address xxx.xxx.xxx.xxx" and  test again

This way I should create tha DHCP server on another LAN, which is the diference with DHCP server local an IP Helper for testing it ?.
