from https://www.debian.org/releases/stable/amd64/apbs02.html.en#preseed-dhcp
if substring (option vendor-class-identifier, 0, 3) = "d-i" {
filename "http://host/preseed.cfg";;

I think that you didn't know that there a two DHCP requests during
a netboot install. One from the bootROM and one from debian-installer.
( CDROM (and USB memory stick) installs only have the d-i DHCP request )
Make sure that your d-i client gets http://192.168.1.1/mountpointisodebian/preseed/myfile.seed
from your DHCP server. Then you can avoid
APPEND url=http://192.168.1.1/mountpointisodebian/preseed/myfile.seed ...

You are welcome. Reporting your milage would be nice.
