upstream PXE boot on GL-iNet routers how?

[xize11]

Hello,

So I'm trying to understand PXE booting and most of it works fine now but I have a little difficulties in getting it to work on a downstream dhcp server on the Brume3.

as for now this is my topology:

is it possible to advertise the same PXE from wan on the lan interface? (10.34.79.0/24) the routes are accessible.

I noticed that the luci is alot more different than on my OpenWrt 25+ build.

which looks as:

please take a note how the checkbox for tftp is not checked, it allows me to sent dhcp options from a third party server on 10.244.244.11 on the Brume3 however it only wants the tftp server which is not what I want.

I already figured it out when my post was in moderation due to image postings

basicly it is the same configuration as upstream on the Flint 2 just this on the Brume3:

/etc/config/dhcp:

config boot 'linux'
    option filename 'iventoy_loader_16000_uefi'
    option serveraddress '10.244.244.11'
    option servername 'tftpserver'
    option force '1'

Luci isn't really helpfull on the older luci on the Brume3, but the configuration is still valid, this will resend the same dhcp options on the lan as upstream, and since the firewall zone has been set to input accept this is possible.
