Howdy!

I have a VM at 172.16.32.4 named CON-MDT running Windows Deployment Services. If I execute the following command on CON-MDT, it succeeds:
tftp -i 172.16.32.4 GET "\boot\x64\wdsmgfw.efi"
If I execute the same command on a different machine (such as my laptop or Intel NUC) it appears to do nothing for a while and then presents a message "Connect request failed".

I have turned off all Windows Firewall profiles on CON-MDT but still get the same results.

I have no issues accessing contents of SMB shares on CON-MDT from either my laptop or Intel NUC.

My Ubiquiti Dream Machine has the DHCP Network Boot Server & Filename and DHCP TFTP Server set to 172.16.32.4, \boot\x64\wdsmgfw.efi, and 172.16.32.4 respectively:

Ideas?

Sound like it's still a windows firewall issue. See if you run a port scanner on an external machine and see if the tftp port is open or not.

is the UDM also your DHCP server?
is this a windows domain environment or is the server standalone?

did you use an admin command prompt to run the tftp test?
what app are you using to test tftp?

UDM is the only DHCP server.
Server is standalone.
I used an elevated administrative Command Prompt when performing the TFTP test.
I am using Microsoft's TFTP Client (https://www.thewindowsclub.com/enable-tftp-windows-10).

Yeah, can you try using a different tftp client? Most linux distros have one built in, i dont know if winscp supports tftp if you need a windows app. Also have you tried doing a pxe boot to that server? What error does that give?

As a standalone mdt server i vaguely recall some settings needing altered, security of the efi file... It will come to me...
