After turning off the firewall on my Ubuntu VM, the install finally worked. I will close this thread and look into the correct firewall configuration.

Hello everyone, I have a problem concerning PXE-Boot when using fog.

I followed the setup instructions on docs.fog.org and was able to succesfully install fog on an Ubuntu VM which is connected to the network via a bridge. On the DHCP-Server, option 66 is set to the IP of the FOG-Server and 67 is set to snponly.efi.

However when I try to PXE boot via a PC I get following error:

Start PXE over IPv4 on MAC: C0-25-A5-88-F5-03
Station IP address is 192.168.1.168

Server IP address is 192.168.1.64
NBP filename is snponly.efi
NBP filessize is 0 Bytes
PXE-E18: Server response timeout.

I am kind of stuck and don’t know how to proceed anymore, any help would be appreciated. Thanks in advance.
