iPXE chainload to 'gpxelinux.0' freeze at '209:string' request

[lvii]

Hi,

I use iPXE with dynamic boot menu with a chainload to 'gpxelinux.0' menu entry to boot PXELINUX with HTTP boot menu.

After iPXE chainload, gpxelinux.0 freeze at request for '209:string' boot menu config file.

But backend web app not receive gpxelinux.0 request.

OS and package: CentOS7 x86_64 with syslinux-4.05-12.el7.x86_64

iPXE chainload to gPXE menu entry :

Code:

:static
set 210:string http://${next-server}/pxe/
set 209:string http://${next-server}:5000/pxelinux/${net0/mac}
echo __INFO: chain ${210:string}gpxelinux.0
echo __INFO: ${209:string}
sleep 2
chain --replace --autofree ${210:string}gpxelinux.0 ||
