<br>
thanks, it’s working fine for me now. Before releasing 2.76, it would be good if more people could test this on actual hardware.<br>
Also, there’s one more item that needs to go into the release notes: we now redirect all clients to port 4011, including the BIOS clients. This is a change in behavior over the previous release, where the option 43 menu was sent on port 68. This could potentially break things for some very old and broken PXE implementations. It’s unlikely, since the port 4011 stuff has always been part of the PXE spec, but possible. I don’t think it’s really necessary, but I have included a patch below that restricts the port 4011 redirect to CSA >= 6. With that patch, the PXE behavior for BIOS clients is exactly what it was in older releases.<br>
