[Dnsmasq-discuss] dhcp-proxy and mac address

[Cristiano Cumer]

So,

I have tried this config

dhcp-range=tag:linux,10.10.144.0,proxy,255.255.240.0
dhcp-range=10.10.160.0,proxy,255.255.240.0
#dhcp-range=10.10.112.21,proxy,255.255.240.0

pxe-prompt=tag:linux,"Press F8 for boot menu", 6
pxe-service=tag:linux,x86PC,"netinstall",pxelinux,10.10.20.7
dhcp-hostsfile=/etc/netboot/linux.conf

log-dhcp

but dnsmasq always replies with a PXE packet even if the mac address is unknown.

in this case then the machine boots form the hd as it can't find/use a tftp server.

It works as expected if I add dhcp-ignore=#known to the config but this is not what I want.

I have some windows dhcp servers already configured for network boot to citrix provisioning servers, but sometimes I need to perform other kinds of network boots, and I can't  change the windows dhcp settings. Dhcp-proxy works perfectly but it changes the network boot behavior for all my devices, so the question is: it's possible to specify a list of mac address for the proxy function?
