So all of the sudden Netboot stopped working outside of the building I am in. It used to work and just one day it stopped. Our Network Engineer did a Wireshark and said that the TTL was the issue but that has never changed nor do I know how to even change this. Any ideas would be great as this is the last piece of our environment working.

For us, anytime Netboot has stopped working, it's either been the server just needed a reboot, or someone messed with the IP helpers. Haven't had a Netboot issue in a long time though. My money is on the helpers not being there or that the netboot packets aren't properly being forwarded in a routed network.

Hi Matt,

This sounds like an IP helper address problem.

You know your netboot server is ok, as it is working within the your building. You can verify a client outside of your building can netboot by configuring manually. If this works double check the IP helper addresses.

sudo bless --netboot --server bsdp://10.10.10.10

On HP switches you can verify the ip helper addresses with the following - note we have seen an issue where it didn't work with too many ip helper addresses set.

config
show ip helper-address

Hope this helps.

Lisa.
