Basically, the first stage of chainloading works OK. iPXE is delivered to a client and is up and running. Then, for the next stage - a script delivery, client timeout occures.</div>

The results are the same. So, tftp service is not a rootcause. </div>

BTW. Although there are multiple tutors how to use dnsmasq for PXE based on pxe-boot configuration, so OpenWRT Luci interface as well, I have never managed to run dnsmasq this way. For me only pxe-serivce in /etc/dnsmasq.conf file worked.</div>
