Can ISC dhcpd operate as a proxy dhcp server for PXE boot?

isc-dhcp

I have an existing LAN with a DHCP server already dishing out IP addresses.

For various reasons I cannot replace that server so it will still need to dish out IP addresses.

I've been experimenting with dnsmasq in proxy mode to provide PXE boot filenames. Now I have dnsmasq chainloading iPXE ok, but I found that the problem with dnsmasq is that in proxy mode it won't send dhcp options down. So I can't seem to send option 17 to boot iscsi san. I read somewhere that it's not enabled in the source code. Oh well, so I thought perhaps I should try isc dhcpd (default version4 with ubuntu). But I can't find any configuration examples that work as a proxy. Does isc dhcpd even work in proxy mode? examples on the web imply patching the source.

What other options do I have?

Maybe it's me but I find it easier to manage my simple pxeboot server just by editing the default file under /tftpboot/pxelinux.cfg.
