Hi Dirk,
Thanks for your input and help.
I have managed to make this work and it seems it was a mixture of removing the DHCP from my virtual network and also tinkering with SELinux. Strangely the firewall never seems to have been an issue but the strange thing is that I had to “enable” in.tftpd as when I started it manually something stops it periodically?
We can now marked this issue as solved.
