Disable DHCP proxy in dnsmasq

Overview

Dnsmasq is used as either a DHCP server or DHCP proxy server for PXE metal provisioning.

Proxy mode is enabled by default allowing the use of existing DHCP servers on the network. A good description on how DHCP Proxy works can be found on the related FOG project wiki page.

Disabling Proxy mode

Certain scenarios will require this project to use a DHCP server, such as an air-gap deployment or dedicated VLAN.

To disable proxy mode thereby using dnsmasq as a DHCP server, modify metal/roles/pxe_server/defaults/main.yml and set dhcp_proxy to false.
