Unable to PXE boot Fortigate 100F

[JDetlor]

Hello, i was wondering if anyone could help me out with a PXE issue i am having. We get the device to get an IP address from DHCP then is says "Downloading NBP file" and does nothing. Just sits there and doesnt even error out. 

I have already set the next-server and filename in the dhcp server.

set next-server 10.200.87.25
set filename "\SMSImages\GSB0023B\winpe.GSB00052.GSB0023B.wim"

Thanks in advanced.

Hi,

guessing this is some device, laptop or some smaller device, then try to do a packet capture on FortiGate. If the device is downloading, there should be a bunch of packets going forth and back.

diag sniffer packet any 'port 69' 4 0 a

will give you the packet headers and sizes (=length) as well as which interface a packet enters and exits.

Hope this helps.

Best regards,

Markus

Thanks for the replies on this issue. I have tried what Markus_M and jiahoong112 has suggested but am still not able to get past this point. I did however get on a call with Fortinet support last week and they have told me that the problem isnt with the 80F device that we are using and that it is passing the traffic correctly. I will investigate further to find the cause of the issue.

Thanks All
