Subject: AW: [dhcwg] Proxy DHCP on port 4011

Hi,

 it is not mandatory to run a DHCP Proxy Service.
Most vendors provide information what options
need to be configured on a DHCP server so it delivers
all the PXE extensions options that the PXE client
requires to operate correctly with the Boot Server 
they deliver.

 Depending on your environment you might not want
to give the PXE administrators permission to modify 
your DHCP configuration or you don't want to reconfigure 
your DHCP server on behalf of the PXE admins all the time.
Using a DHCP Proxy Service seperates "normal" DHCP
administration and PXE administration. 

Regards,
 Thomas
