[Dnsmasq-discuss] Proxydhcp only for specific clients

since yesterday i set up my ubuntu ltsp server plus dnsmasq configured as a proxydhcp.

My Problem is that every client which boots via pxe uses the proxydhcp. I use already a DHCP Server where some clients get a "next-server" option to boot from a OpenSuse ltsp.

With my Ubuntu ltsp running every client which normally uses the OpenSuse LTSP is now using the Ubuntu one.

In the dnsmasq.conf it says something like:
# If another DHCP server is present on the network, you may use a proxy range
# instead.
Is there some special syntax for a proxy range?

This is my dnsmasq.conf:

# Configures dnsmasq for PXE client booting.
# All the files in /etc/dnsmasq.d/ override the main dnsmasq configuration in
# /etc/dnsmasq.conf.
# You may modify this file to suit your needs, or create new ones in dnsmasq.d/.

# Log lots of extra information about DHCP transactions.

# IP ranges to hand out.

# If another DHCP server is present on the network, you may use a proxy range
# instead. This makes dnsmasq provide boot information but not IP leases.
# (needs dnsmasq 2.48+)

# The rootpath option is used by both NFS and NBD.

# Define common netboot types.
dhcp-vendorclass=ltsp,"Linux ipconfig"

# Set the boot filename depending on the client vendor identifier.
# The boot filename is relative to tftp-root.

# Kill multicast.

# Disable re-use of the DHCP servername and filename fields as extra
# option space. That's to avoid confusing some old or broken DHCP clients.

# We don't want a PXE menu since we're using a graphical PXELinux menu.
#pxe-prompt="Press F8 for boot menu", 3

# The known types are x86PC, PC98, IA64_EFI, Alpha, Arc_x86,
# Intel_Lean_Client, IA32_EFI, BC_EFI, Xscale_EFI and X86-64_EFI
pxe-service=X86PC, "Boot from network", /ltsp/i386/pxelinux

# A boot service type of 0 is special, and will abort the
# net boot procedure and continue booting from local media.
#pxe-service=X86PC, "Boot from local hard disk", 0

# Comment the following to disable the TFTP server functionality of dnsmasq.

# The TFTP directory. Sometimes /srv/tftp is used instead.

# Disable the DNS server functionality of dnsmasq by setting port=0

# Don't listen on lo, to prevent conflicts with Ubuntu's local resolver hack (LP: #959037).
