TFTP-proxy
Trivial File Transfer Protocol (TFTP) is a simple form of FTP that uses very small amounts of memory. It is
used to transfer small files between hosts on the same network. Some manufacturers use the TFTP
protocol to send periodic updates to VoIP equipment under management. If your equipment requires
TFTP for updates, make sure you add a TFTP policy to your Firebox configuration to allow these
connections.
