16.7 Legacy Series / Re: TFTP blocked

the problem is that the server answers the request from a different port (see https://tools.ietf.org/html/rfc1350) and the firewall usually will block that because from its point of view this is a new connection which is not allowed.
If your policy allows that, you can try to pass any UDP traffic from your TFTP server.
