[Dnsmasq-discuss] DHCP Proxy Problem

[Joe Giles]

Hi again list,

I have a PXE boot connection issue with machines on my network. Here is a little techical data:

1. PXE/DHCPProxy server - 10.226.152.70
2. MS DHCP Server 10.226.152.16
3. Using HP Procurve switches

I have DHCP Option 066 set in MS DHCP proxy to point to my PXE/DHCPProxy server (10.226.152.70).

I have added helper IPs to the procure switch because they are on a different vlan. I added the MS
DHCP server and the PXE/DHCPProxy server address as a helper IP as well.

When I launch dnsmasq, I get errors stating:

dnsmasq-dhcp[9710]: no address range available for DHCP request via 10.226.77.254 - Which is the gateway for the vlan.
But I also get:

dnsmasq-dhcp[9710]: no address range available for DHCP request via 10.226.77.253 - Which is the switch for the vlan.

My host never hits the PXE/DHCPProxy server, and I verified by using wireshark.

Here is the config for dnsmasq:


port=0
interface=eth0
listen-address=10.226.152.70,127.0.0.1
log-dhcp
tftp-root=/var/lib/tftpboot
dhcp-ignore=tag:tobeignored
dhcp-boot=pxelinux.0
dhcp-option=vendor:PXEClient,6,2b
dhcp-no-override
pxe-prompt="Press F8 for boot menu", 0
pxe-service=X86PC, "Boot from network", pxelinux
pxe-service=X86PC, "Boot from local hard disk", 0
dhcp-range=10.226.152.70,proxy
dhcp-mac=set:tobeignored,00:30:6E:4A:42:43
dhcp-mac=set:tobeignored,00:30:6E:0C:7A:C2


I think I have something not configured proporly, but have no idea what that could be. When I was testing this in my own
network area (No switches), it worked just fine. But I am not sure if there is extra configuration needed on the switches, 
dnsmasq, or MS DHCP server.

Can someone give me an idea where to look?

Thanks!
Joe
