TFTP communicating on High Ports

Shawnm14,

Data transfer is initiated on port 69, but the data transfer ports are chosen independently by the sender and receiver during initialization of the connection. The ports are chosen at random according to the parameters of the networking stack, typically from the range of Ephemeral ports.

See this link for information on Ephemeral ports:
en.wikipedia.org/.../Ephemeral_ports

You will need to keep the Ephemeral port range open.

--HTH

Steve
