I'm trying to configure a PXE boot server, but the DHCP is on a separate machine. I have 2 WDS servers already running, and they can be chosen in the boot menu. But this freshly configured Linux machine doesn't show up.

I combined various guides and read up on the docs

Any suggestions to how I can make this work are appreciated

/etc/dnsmasq.conf

interface=eth0,lo
bind-interfaces

# Specify TFTP Options #

#--location of the pxeboot file
dhcp-boot=bios/pxelinux.0

#--enable tftp service
enable-tftp

#-- Root folder for tftp
tftp-root=/tftp

#--Detect architecture and send the correct bootloader file
dhcp-match=set:efi-x86_64,option:client-arch,7 
dhcp-boot=tag:efi-x86_64,grub/bootx64.efi
