The Trivial File Transfer Protocol (TFTP) ALG processes TFTP packets that initiate the request to UDP destination port 69 and opens a gate to allow return packets from the reverse direction to the port that sends the request. Support of stateful firewall and NAT services requires that you configure the TFTP ALG for UDP destination port 69.
