[Dnsmasq-discuss] DHCP Proxy and UEFI HTTP boot

[michael at albert-hetzles.de]

Hi dnsmasq-discuss Groupmembers,

I tried to get working dnsmasq as DHCP Proxy for UEFI HTTP boot.

The following configuration, dnsmasq as DHCP Server, works (but we have 
another DHCP Server running):

dhcp-range=efi-http,192.168.1.200,192.168.1.220

dhcp-option=tag:efi-http,option:vendor-class,HTTPClient
dhcp-option=tag:efi-http,option:bootfile-name,http://192.168.1.100/esxi/mboot.efi

But when i tried to setup dnsmasq as  DHCP Proxy it does not respond to 
any requests:

dhcp-range=efi-http,192.168.1.0,proxy,255.255.255.0

dhcp-option=tag:efi-http,option:vendor-class,HTTPClient
dhcp-option=tag:efi-http,option:bootfile-name,http://192.168.1.100/esxi/mboot.efi

After further investigations I found out that dnsmasq does only responds 
(send packets) to DHCP Requests, when configured as DHCP Proxy, when the 
options  pxe-service and dhcp-boot are set (to some "default", useless 
values, and therefore UEFI HTTP Boot not work). But in my opinion these 
options are not necessary for booting UEFI HTTP Clients and makes no 
sense to set.

Anybody a hint for me whats wrong in my configuration? Or is the 
combination DHCP Proxy and UEHI HTTP boot not RFC like?

THx in advance

Michael
