The DHCP server will only reply with DHCP options the client requested. So check the DHCP request if code 66 was requested.
Code 66 is equivalent to next-server (DHCP header) Code 67 is equivalent filename (DHCP header)
In theory, both should working. However during my tests. most PXE clients ignored Code 66.
So please create a DHCP option for next-server and configure them. If the client then uses the correct tftp server but wrong filename, please create an entry for filename too.
using next-server instead of option 66 I'm getting further and: to another problem.
I'm using "BStrap\X86pc\BStrap.0" in the text field of option 67 (or option "filename"). Via wireshark I can see only "BStrapX86pcBStrap.0" where in my prodlan also the backslashes are presented.
so in short: could it be that the backslashes in dhcp option textfields are deleted/ignored by astaro?
when moving the file down two folders in the "root" and therefore avoiding the backslashes it works!!! at last!
