ipxe boot slow after changing to HTTPS

• like a packet from a different connection (but on the same ports!)

This could be the NAT’d VM IP. I ran wireshark on the Default Hyper-V Switch adapter.

If the first test is instant but the second one is delayed we seem to have an iPXE issue - on the one hand I have never seen this on my HTTPS setups but also this is the most likely outcome from my perspective.

So this is what we are at right now, right?? And you tested this on different machines, VMs as well as hardware.

I will try to replicate the issue. If I can’t we should schedule for a debug session together some time next week.

@Sebastian-Roth Definitely looks like it is isolated to ipxe.

Out of curiosity, what NICs do you typically run ipxe on?

[Sebastian Roth]

@brakcounty Didn’t find the time to test on my side yet. Will do in the next days and let you know.

@Sebastian-Roth Cool thanks, much apppreciated. By the way, this isn’t an operation-breaking critical issue, so take your time.

@brakcounty I still have not found enough time to do a test setup…

The default on Linux virtualbox: Intel PRO/1000 MT Desktop (82540EM)

Hmm. Assuming you’re booting legacy pxe instead of UEFI, since UEFI PXE boot on Vbox requires the Paravirtualized Network Adapter (virtio) adapter. Not that it made make a difference for me at least once ipxe is loaded.

Yes, legacy. Because I never got UEFI PXE booting to work in vbox on Linux.

Even when using the Paravirtualized Network Adapter in VBox?

Learning something new every day! Wow, didn’t know this and never tried it before. Thanks!!!
