For the first time I have had the need to use tftp over a firewall.
I knew that port 69 was involved on the server side but what I did not know was that the data transfer is done over a new connection from client to server on a dynamic port!
But luckily with tftpd32 I was able to specify the local port pool and I have set it to 69:69. This worked like a charm.
